AB  - This paper presents sustainable technology for environmentally friendly composite production. Biobased unsaturated polyester resin (b-UPR), synthesized from waste polyethylene terephthalate (PET) glycosylate and renewable origin maleic anhydride (MAnh) and propylene glycol (PG), was reinforced with unmodified and vinyl-modified biosilica nanoparticles obtained from rice husk. The structural and morphological properties of the obtained particles, b-UPR, as well as composites, were characterized by Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (NMR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) techniques. The study of the influence of biosilica modification on the mechanical properties of composites was supported by hardness modeling. Improvement of the tensile strength of the b-UPR-based composite at 2.5 wt.% addition of biosilica modified with vinyl silane, named “b-UPR/SiO2-V” composite, has been achieved with 88% increase. The thermal aging process applied to the b-UPR/SiO2-V composite, which simulates use over the product’s lifetime, leads to the deterioration of composites that were used as fillers in commercial unsaturated polyester resin (c-UPR). The grinded artificially aged b-UPR composites were used as filler in c-UPR for the production of a table top layer with outstanding mechanical properties, i.e., impact resistance and microhardness, as well as fire resistance rated in the V-0 category according to the UL-94 test. Developing sustainable composites that are chemically synthesized from renewable sources is important from the aspect of preserving the environment and existing resources as well as the extending their life cycle.

AB  - Efficient cathodes for the hydrogen evolution reaction (HER) in acidic water electrolysis rely on the use of expensive platinum group metals (PGMs). However, to achieve economically viable operation, both the content of PGMs must be reduced and their intrinsically strong H adsorption mitigated. Herein, we show that the surface effects of hydrogenated TiO2 nanotube (TNT) arrays can make osmium, a so far less-explored PGM, a highly active HER electrocatalyst. These defect-rich TiO2 nanostructures provide an interactive scaffold for the galvanic deposition of Os particles with modulated adsorption properties. Through systematic investigations, we identify the synthesis conditions (OsCl3 concentration/temperature/reaction time) that yield a progressive improvement in Os deposition rate and mass loading, thereby decreasing the HER overpotential. At the same time, the Os particles deposited by this procedure remain mainly sub-nanometric and entirely cover the inner tube walls. An optimally balanced Os@TNT composite prepared at 3 mM/55 °C/30 min exhibits a record low overpotential (η) of 61 mV at a current density of 100 mA cm–2, a high mass activity of 20.8 A mgOs–1 at 80 mV, and a stable performance in an acidic medium. Density functional theory calculations indicate the existence of strong interactions between the hydrogenated TiO2 surface and small Os clusters, which may weaken the Os–H* binding strength and thus boost the intrinsic HER activity of Os centers. The results presented in this study offer new directions for the fabrication of cost-effective PGM-based catalysts and a better understanding of the synergistic electronic interactions at the PGM|TiO2 interface.

AB  - The mean ionic activity coefficients of NaCl in a ternary system {yNaCl + (1 – y)Na2HPO4}(aq) were determined from measurements of the electromotive force (EMF) where the NaCl ionic strength fraction was y = (0.3012; 0.4015; 0.5011; 0.5988; 0.7706; 0.8997) in the range of total ionic strength of the solution Im = 0.0701–1.0161 mol kg–1 at temperature T = 298.15 K.

The differences in the osmotic coefficients between the estimated and experimental values were negligible.

AB  - Low-cost and easily available natural zeolite is a promising adsorbent for metal ions removal in wastewater treatment. The possibility of using zeolitic tuff from Serbia in the form of Na-enriched natural zeolite (Na-Z) for the adsorption of Pb2+, Zn2+, Cu2+, and Ni2+ ions from wastewater was investigated in the presented paper. The research included Na-Z characterization and determination of adsorption kinetics in individual ion adsorption tests using Weber-Morris intraparticle diffusion model, non-linear pseudo-first-order (PFO), pseudo-second-order (PSO) and mixed-order (MO) kinetic models. The results indicate that the adsorption processes of metal ions on Na-Z are complex processes dominated by multiple rate-limiting mechanisms and best defined by the MO model. The mechanisms of ion diffusion and adsorption to active sites are equally represented in the Pb2+ adsorption process. The mechanism of ion adsorption on the active sites is the rate-limiting step in the Zn2+ adsorption process, while in the case of the Cu2+ and Ni2+ adsorption ion diffusion is the rate-limiting kinetic mechanism. Within the MO model, the PFO rate (external/internal diffusion) and the PSO rate (adsorption on active sites) were calculated and results were applied to a multicomponent wastewater sample in order to determine and explain the adsorption efficiency in wastewater treatment. The results show that the rate of adsorption of individual metal ions and the efficiency of ion removal from a multicomponent wastewater sample are influenced by several factors including the radius of the hydrated ion and the free energy of hydration. The achieved removal of metal ions by Na-Z is Pb2+ (89%) > Cu2+ (72%) > Zn2+ (61%) > Ni2+ (58%) and defines Na-enriched natural zeolite as an effective adsorbent in wastewater treatment.

The cell of the type K–ISE|KCl(mKCl), KH2PO4(mKH2PO4)|Ag|AgCl was used in the total ionic strength range, Im = 0.0886–1.0046 mol kg–1. In order to generate a set of parameters that can be applied in a wide range of mixed solution ionic strengths, the Pitzer, Scatchard, and Clegg–Pitzer–Brimblecombe models were used to fit all available experimental data, including cell potential and isopiestic measurements from the literature. The experimental and calculated values of thermodynamic properties for the studied system are in excellent agreement. Potential interactions and solution structure were discussed by means of the excess free energy of mixing via potential pairs, triplets, or quads for the investigated solution using the Scatchard model mixing parameters.

AB  - Multifunctional lignin bio-based adsorbent, b-LMS, was obtained via inverse copolymerization in the suspension of acryloyl modified kraft lignin (KfL-AA) and bio-based trimethylolpropane triacrylate (bio-TMPTA). Morphological and structural characterization of KfL-AA and b-LMS was performed using BET, FTIR, Raman, NMR, TGA, SEM, and XPS techniques. The b-LMS microspheres with 253 ± 42 μm diameters, 69.4 m2 g−1 surface area, and 59% porosity efficiently adsorb Malachite Green (MG), Tartrazine (T), and Methyl Red (MR) dye. The influence of pH, pollutant concentration, temperature, and time on the removal efficiency was studied in a batch mode. Favorable and spontaneous processes with high adsorption capacities e.g. 116.8 mg g−1 for MG, 86.8 mg g−1 for T, and 68.6 mg g−1 for MR indicate the significant adsorptive potential of b-LMS. Results from diffusional and single mass transfer resistance studies indicate that pore diffusion is a rate-limiting step. Theoretical calculations confirmed a higher affinity of b-LMS to cationic dye MG compared with an anionic and neutral one, i.e. T and MR, respectively.

Developed methodology implements the principle of sustainable development and offers concept whose results contribute to the minimization of environmental pollution.

AB  - More than 90 % of lead produced in Europe comes from secondary lead flows, of
which 85 % is attributed to waste lead-acid batteries (LAB). The main technological
approach for LAB processing implies pyrometallurgy by which 100–400 kg of waste slag
(WS) is generated per 1 ton of produced metallic lead. Due to recycling process parameters,
generated WS has great potential for releasing toxic elements contributing to environmental
pollution [1]. Namely, the most common flux in the recycling process is sodium-based
(Na2CO3) when alkali lead waste slag (ALWS) is generated, characterized as hazardous due
to its physical-chemical characteristics: high leachability, hygroscopic and pulverized
nature and, ultimately, instability [2,3]. Therefore, ALWS treatment prior to disposal should
be considered an integral part of waste LAB treatment systems. Immobilization of toxic
elements contained in slag is crucial and can be achieved by stabilization/solidification
processes (S/S) as one of the most widely used technologies in the treatment of heavy metal containing wastes for final disposal or utilization.
In this research, ALWS generated in the waste LAB recycling is used to determine
the S/S process efficiency as a function of the added binder amount (cement, in the range of
5 – 10 %), pre-treatment (the removal of water-soluble compounds), and activator addition
(MgO). The liquid to solid (L/S) ratio was 1/4 in all S/S experiments. The basic parameters
for the effectiveness assessments were compressive strength (UCS) and pollutants leaching
(Method 1311 Toxicity characteristic leaching procedure, TCLP).
The conclusion is that, contrary to the pre-treatment process, the addition of MgO has
an overall positive effect on the S/S process of ALSW, ensuring both mechanical and
chemical stability. This ALWS solidificate, obtained through the S/S process by using MgO
as an activator, is safe for disposal, according to environmental regulations.

AB  - Natural zeolite is a good sorbent for many cations due to its specific porous structure. The degree of sorption efficiency depends on the cation type and the availability of exchange positions in the zeolite lattice. The aim of this work is to
examine the synthesis possibility of a new adsorbent based on natural zeolite and hydroxyapatite. The adsorbent was prepared mechanochemically by using clinoptilolite-rich zeolite tuff from the Slanci deposit (Serbia) and hydroxyapatite
obtained by the hydrothermal process. The milling process was performed in a ball mill and optimized regarding contact time and milling speed. For the synthesis of zeolite/hydroxyapatite adsorbent (ZHAp), optimal values for these two parameters were 10 min and 250 rpm, respectively. The resulting sample ZHAp was characterized by X-ray powder diffraction, thermal analysis and scanning electron microscopy. Diffraction analysis of the ZHAp confirmed the presence of the most abundant mineral in zeolite tuff - clinoptilolite and hydroxyapatite. Needle-like crystals of hydroxyapatite on the clinoptilolite surface are observed in SEM images. Zeolite/hydroxyapatite sample is thermally stable at 800 °C. Adsorption properties of ZHAp were examined for nickel and chromium ions, towards which natural zeolite shows a low affinity. The presence of hydroxyapatite on the zeolite surface led to an increase in the adsorption capacity more than two times for both tested ions compared to the initial zeolite tuff.

AB  - During the conventional roast–leach–electrolysis (RLE) zinc production process, precipitation of the jarosite-type compounds is widely used to remove iron and other metal impurities from the solution. Above mentioned compounds, with the general formula MFe3(SO4)2(OH)6, (M+=NH4, Na, K, Ag, etc.), in addition to iron, contain a high concentration of Pb, Cd, Cr, As, Zn, In, Ga, Ge as metal oxides and/or sulfates [1]. Consequently, jarosite is considered hazardous yet valuable waste [2]. In addition, every year around 6-7 million tonnes of jarosite waste is generated globally [3]. Due to large waste volumes and its chemical characteristics, jarosite requires a lot of storage space and monitoring. Unfortunately, this type of waste is often landfilled causing serious environmental problems and irreversible metal and value losses. Hence, an urgent solution for both managing and utilization/recycling is required, to face needs regarding ecological demands and circular economy goals.
In this paper, jarosite sludge, as a specific type of hazardous industrial waste, is used to investigate transformation to the targeted compounds through the comprehensive thermodynamic analysis and experimental roasting process tests. The roasting was conducted to transform iron into insoluble hematite (Fe2O3), valuable metals (Zn, Cu, and In) into water-soluble sulfates, and to keep Pb in the form of water-insoluble anglesite (PbSO4). The solid residue obtained after roasting was used in leaching tests to further evaluate the efficiency of the targeted phase transformations.
Theoretical considerations of chemical reactions and phase thermodynamics were performed using the HSC Chemistry v.9.2.3 software [4] to define potential chemical reactions, examine the feasibility of the target transformations, and set the limiting reaction parameters. Further, in the first part of the experimental work, the influence of the roasting process and reaction parameters on the transformation of jarosite sludge phases into target compounds was investigated. This included variations in the reaction time, temperature, and furnace atmosphere influence. The leaching conditions were kept constant (temperature of 25 °C, during 60 min, and solid to liquid ratio of 1/5) to determine the efficiency of phase transformations in the samples obtained by roasting. Changes in the chemical and mineralogical composition and microstructure were analyzed using different analytical methods, including XRD and SEM analysis.
According to the obtained results of the roasting process, it was determined that the phase transformation of jarosite sludge compounds into targeted insoluble hematite and water-soluble sulfates occurs at 730 °C, the time required is 60 min in the air (oxidizing) atmosphere of 1-2 [dm3/h]/kg of the input material, which is in accordance with the results of the theoretical indications. Also, it is experimentally confirmed that the introduction of sulfate into the roasting
 
atmosphere leads to the incomplete transformation of jarosite and the formation of the unwanted Fe2(SO4)3. Leaching results of the sample obtained by the abovementioned optimal roasting conditions show that only 4.5% of Fe is leached while the rest remains as solid targeted hematite. Also, more than 75% of In and more than 90% of other targeted metals (Cu and Zn) are leached, indicating the high efficiency of the roasting process. Phase transformation was confirmed by SEM analysis, showing that hexagonal crystals of jarosite, dominating in the starting material, were completely replaced with the globular microstructure of Fe2O3, in the roasted samples. SEM analysis of the leaching residue also confirmed the absence of the water-soluble sulfates and the presence of the anglesite as water-insoluble sulfate. The phase composition of the samples is confirmed by XRD analysis.
This research shows that the proposed process enables the recycling of jarosite through metal transformation and further utilization. The obtained products can be used in industry, while the metal ions can be selectively separated from the sulfate solution and returned to the production streams. This approach contributes to the utilization of jarosite, as hazardous waste, in order to obtain valuable metals, and generally reduces the negative environmental impact by decreasing the amount of disposed waste and reducing the need for primary exploitation.

This included variations in the reaction time, temperature, and furnace atmosphere influence. The leaching conditions were kept constant (temperature of 25 °C, during 60 min, and solid to liquid ratio of 1/5) to determine the efficiency of phase transformations in the samples obtained by roasting. Changes in the chemical and mineralogical composition and microstructure were analyzed using different analytical methods, including XRD and SEM analysis.
According to the obtained results of the roasting process, it was determined that the phase transformation of jarosite sludge compounds into targeted insoluble hematite and water-soluble sulfates occurs at 730 °C, the time required is 60 min in the air (oxidizing) atmosphere of 1-2 [dm3/h]/kg of the input material, which is in accordance with the results of the theoretical indications. Also, it is experimentally confirmed that the introduction of sulfate into the roasting
 
atmosphere leads to the incomplete transformation of jarosite and the formation of the unwanted Fe2(SO4)3. Leaching results of the sample obtained by the abovementioned optimal roasting conditions show that only 4.5% of Fe is leached while the rest remains as solid targeted hematite. Also, more than 75% of In and more than 90% of other targeted metals (Cu and Zn) are leached, indicating the high efficiency of the roasting process. Phase transformation was confirmed by SEM analysis, showing that hexagonal crystals of jarosite, dominating in the starting material, were completely replaced with the globular microstructure of Fe2O3, in the roasted samples. SEM analysis of the leaching residue also confirmed the absence of the water-soluble sulfates and the presence of the anglesite as water-insoluble sulfate. The phase composition of the samples is confirmed by XRD analysis.
This research shows that the proposed process enables the recycling of jarosite through metal transformation and further utilization. The obtained products can be used in industry, while the metal ions can be selectively separated from the sulfate solution and returned to the production streams. This approach contributes to the utilization of jarosite, as hazardous waste, in order to obtain valuable metals, and generally reduces the negative environmental impact by decreasing the amount of disposed waste and reducing the need for primary exploitation.",

AB  - More than 90% of lead produced in Europe comes from secondary lead flows, of which 85% is attributed to waste lead-acid batteries (LAB). The main technological approach for LAB processing implies pyrometallurgy by which 100–400 kg of waste slag (WS) is generated per 1 ton of produced metallic lead. Due to recycling process parameters, generated WS has great potential for releasing toxic elements contributing to environmental pollution [1]. Namely, the most common flux in the recycling process is sodium-based (Na2CO3) when alkali lead waste slag (ALWS) is generated, characterized as hazardous due to its physical-chemical characteristics: high leachability, hygroscopic and pulverized nature and, ultimately, instability [2,3]. Therefore, ALWS treatment prior to disposal should be considered an integral part of waste LAB treatment systems. Immobilization of toxic elements contained in slag is crucial and can be achieved by stabilization/solidification processes (S/S) as one of the most widely used technologies in the treatment of heavy metal-containing wastes for final disposal or utilization.
In this research, ALWS generated in the waste LAB recycling is used to determine the S/S process efficiency as a function of the added binder amount (cement, in the range of 5 – 10 %), pre-treatment (the removal of water-soluble compounds), and activator addition (MgO). The liquid to solid (L/S) ratio was 1/4 in all S/S experiments. The basic parameters for the effectiveness assessments were compressive strength (UCS) and pollutants leaching (Method 1311 Toxicity characteristic leaching procedure, TCLP).
ALWS containing 3.5 Pb, 15.5 Na, 14.0 S, and 24.7 Fe was mixed with cement and water. The results of UCS showed that all produced solidificates exceeded the required value of 0.35 MPa [4], yet the mixture containing 7.5 % of the cement has the best mechanical properties (2.1 MPa). This sample was further analyzed and the TCLP results showed that the Pb concentration exceeds the limit values for stabilized slag (10.4 and 5 ppm, respectively). In the next set, ALWS was pre-treated by continuous rinser (30 ºC, 60 min, L/S 4). Obtained results of UCS (0.4 MPa) and TCLP (53.4 ppm) were unfavorable. The last set, besides the binder, included activator addition (MgO, 7.5 %) altogether with a high content of untreated ALWS (85 %). Analysis of the produced solidificates showed favorable and acceptable results (USC - 3.3 MPa, TCLP – Pb 4.5 ppm). 
Generally, in an alkaline slag-leaching solution lead precipitates as a complex mixture (PbO, Pb(OH)2, PbO×Pb(OH)2). Lead oxides are amphoteric and dissolve in an alkaline aqueous solution, leading to poor solidification. Also, lead present in surface coatings around cement grains prevents cement hydration. Simultaneously, the migration of lead to the surrounding water is promoted. The negative effect of the pre-treatment is a consequence of the sulfate ions absence, as well as the absence of the ettringite (Ca6Al2(SO4)3(OH)12×26H2O) and sulfate- AFm phases [5], which negatively affect the strength of the product. The addition of MgO benefits the S/S process through hydrotalcite-like phase formation ([M1-
2+M 3+(OH) ][A   n-×mH O], M2+=Mg, Zn, Ni, Fe; M3+=Al, Cr, Fe; A=CO 2-,
NO -, Cl-), a compound capable of metal adsorption, hence immobilization [6].
The conclusion is that, contrary to the pre-treatment process, the addition of MgO has an overall positive effect on the S/S process of ALSW, ensuring both mechanical and chemical stability. This ALWS solidificate, obtained through the S/S process by using MgO as an activator, is safe for disposal, according to environmental regulations.

AB  - N-doped TiO2/carbon composites (TiO2/CN) with different nitrogen content, were obtained starting from titanium isopropoxide and glucose, and by varying the amount of melamine, added to starting reaction mixture. For com­parison, an undoped sample (TiO2/C) was also prepared. Structural and surface characteristics were determined through scanning electron microscopy, thermo­gravimetric analysis, elemental analysis, Fourier transform infrared spectro­scopy, X-ray photoelectron spectroscopy, X-ray diffraction and nitrogen ads­orption–desorption isotherms. The photocatalytic activity of TiO2/CN com­posites was examined via photocatalytic degradation of methylene blue and multiclass pharmaceuticals from water solution. It was found that N doping of TiO2/carbon composites induced changes in structural and surface character­istics of TiO2/CN composites, improving their adsorption, but decreasing photocatalytic efficiency. Nevertheless, TiO2/CN0.05 composite obtained by the hydrothermal synthesis in the presence of glucose and 0.05 g melamine showed the highest efficiency for removing selected pharmaceuticals and methylene blue from aqueous solutions through the combined processes of adsorption in the dark, and photocatalytic degradation under UV and visible irradiation.

AB  - Orange single crystals of new polymeric cobalt(II) complex {[Co(bipy)(H2O)4]2[Co(μ-mell)(H2O)2 ]·
10H2 O}n, 1, were synthesized by slow evaporation method at room temperature (bipy = 2,2′-bipyridine,
mell = hexaanion of mellitic acid) and its crystal structure was determined by single-crystal X-ray diffrac-
tion. The complex 1 was characterized based on elemental analysis, FTIR spectroscopy and thermal
(TG/DTA) analysis followed by computational analysis of noncovalent interactions and quantum chemical
calculations of interaction energies. In 1, two crystallographically different Co(II) atoms adopt a deformed
octahedral geometry, while bridging mell acts as a tetrakis monodentate ligand allowing the development
of wavy-like anionic chains running along [100] direction. The 3D supramolecular network of 1 is com-
posed of alternating supramolecular and water layers connected by hydrogen bonds. The supramolecular
layer is formed of ionic interactions between complex cations and polymeric complex anions, established
mainly through O–H···O hydrogen bonds, as well as stacking interactions between bipy ligands, while the
water layers are comprised of hydrogen bonded lattice water molecules. Upon heating up to 1200 °C
in nitrogen and air atmosphere, complex 1 showed multiple-step degradation that resulted in the for-
mation of Co and Co3O4, respectively. Computed Hirshfeld surfaces and 2D fingerprint plots indicated
that O–H···O hydrogen bonds are the most dominant in the crystal structure, while the shape index and
curvedness mapped on the Hirshfeld surfaces of 1 revealed that stacking interactions have an important
role in the stabilization of the crystal packing. Quantum chemical calculations showed that, aside from
ionic hydrogen-bonded interaction between cation and anionic polymer, the important role in the sta-
bility of supramolecular structure of 1 is played by hydrogen bonds of cation and anionic polymer with
lattice water, as well as by stacking interactions between bipy ligands.

AB  - A series of twelve novel hybrids of cinnamic acid and thiocarbohydrazones were designed, synthesized in high yield using a simple coupling strategy via acid chlorides, and evaluated for their impact against Mycobacterium tuberculosis (Mtb) and cancer cells survival. Among them, compound 3 demonstrated strong anti-Mtb activity by reducing bacilli survival for>90 % in all three treated Mtb isolates, whereas isoniazid and rifampicin did not. Moreover, compound 3 didn’t affect vitality of HepG-2 cells, implying on advantageous hepatotoxicity profile compared to current therapeutic options for tuberculosis. Compounds 2a and 3b displayed as strong inducers of apoptosis in A549 cells, both activating intrinsic caspase pathway and cell cycle arrest at the G0/G1 phase. Subsequent analyses disclosed differences in their activities, where 3b has ability to induce production of mitochondrial superoxide anions, while 2a significantly inhibited cellular mobility. More importantly, 3b considerably affected viability of HepG-2 and HaCaT cells, whereas 2a had moderate impact only on the later. Molecular modeling studies indicated high permeability and good absorption through the human intestine, and moderate aqueous solubility with poor blood–brain barrier permeability. In summary, our results reveal that novel compounds 3 and 2a represent promising agents for tuberculosis and cancer treatment, respectively, indicating that further investigation needs to be performed to clarify the mechanisms of their anti-Mtb and anticancer activity.

AB  - The aim of this study was to investigate a possibility of synthesis of porous ceramics with controlled open porosity, which could be used as sorbents and catalyst supports. Two organic additives were used to obtain open porosity: polystyrene beads and cellulose fibers, which are mixed with kaolin clay powder and the appropriate water content. Samples were sintered at 1050 oC for 1 h. Characterization of the obtained products included X-ray powder diffraction analysis (XRPD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and elemental CHNS analysis. In addition, porosity was examined by quantification of visual information. The specific surface areas were determined by the Brunauer–Emmett–Teller (BET) method. Also, density and compressive strength of the obtained samples were assessed. It was determined that by sintering, the organic component completely leaves the system. For samples prepared with polystyrene beads and with cellulose fibers, satisfactory mechanical properties were obtained: compressive strengths were 1.42 and 1.56 MPa, respectively. It was noted that significantly higher open porosity was obtained by using polystyrene beads as a sacrificial template (porosity of ̴56 %) instead of cellulose fibers (porosity of ̴6 %).

AB  - The scope of the present study was to prepare fully bio-based unsaturated polyester resins (UPRs) with comparable properties to the commercial formulations. The focus was set on the determination of the optimal prepolymer formulation using the same set of diacids (itaconic and succinic acid) and different diols (propylene glycol, isosorbide and neopentyl glycol) or its equimolar mixtures, keeping the fixed molar ratio of 1:1:2.1 in all feed compositions. Instead of commonly used styrene, bio-based dimethyl itaconate was used as a reactive diluent (RD). The rheology of the obtained resins was studied in detail. The effect of the used diol on structural (FTIR), thermal (DSC), thermomechanical (DMA), and mechanical (tensile) properties was explained. The properties of UPRs were found to be highly dependent on the diol used in the prepolymer formulation. The UPR with an equimolar ratio of propylene glycol and neopentyl glycol was shown to be the most promising candidate to compete with the commercial petroleum-based resins.

AB  - In-depth kinetic and column adsorption study for diclofenac, DCF, heavy-metal and oxyanions adsorption on highly effective amino-functionalized lignin-based microsphere adsorbent (A-LMS) is examined. The A-LMS was synthesized via inverse suspension copolymerization of industrial kraft lignin with the amino containing grafting-agent (polyethylene imine), and an epoxy chloropropane cross-linker. The batch adsorption results indicated process spontaneity and feasibility of a high removal capacity: DCF(151.13)>>Cd2+(74.84)>Cr(VI)(54.20)>As(V)(53.12)>Ni2+(49.42 mg g−1). The quantum chemical calculated interaction energies reveal stabilization of the A-LMS/DCF complex through the electrostatics and van der Waals interactions. The results from the pseudo-second order and Weber-Morris fitting indicate a fast removal rate; thus, column tests were undertaken. The single resistance mass transfer model, i.e. the mass transfer (kfa) and diffusion coefficient (Deff), shows pore diffusional transport as a rate limiting step. The fitting of the fixed bed column data with empirical models demonstrates the influences of flow rate and adsorbate inlet concentration on the breakthrough behavior. Pore surface diffusion modeling (PSDM) expresses mass transport under applied hydraulic loading rates, calculated breakthrough point adsorption capacities: Cd2+(58.1)>Cr(VI)(54.1)>As(V)(50.9)>>Ni2+(42.9 mg g−1)), without performing the experimentation on a full pilot-scale level, further confirms the high applicability of the A-LMS bio-based adsorbent.

AB  - This research proposed two pretreatments of viscose fabrics: oxidation with 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) and coating with TEMPO-oxidized cellulose nanofibrils (TOCN), to introduce functional groups (COOH and CHO) suitable for irreversible binding of chitosan nanoparticles without and with embedded zinc (NCS and NCS + Zn, respectively) and consequently achieving washing durable antibacterial properties of the chitosan nanoparticles functionalized fabrics. The characterizations of pretreated and chitosan nanoparticles functionalized fabrics were performed by FTIR and XPS spectroscopy, elemental analysis, inductively coupled plasma optical emission spectrometry, zeta potential measurements, scanning electron microscopy, determination of COOH and CHO groups content, and antimicrobial activity under dynamic contact conditions. Influence of pretreatments on NCS and NCS + Zn adsorption, chemical, electrokinetic, and antibacterial properties as well as morphology, and washing durability of NCS and NCS + Zn functionalized fabrics were studied and compared. Washing durability was evaluated through changes in the chitosan and zinc content, zeta potential, and antibacterial activity after 1, 3, and 5 washing cycles. Pretreatments improved washing durability of antibacterial properties of chitosan nanoparticles functionalized fabrics. The NCS and NCS + Zn functionalized pretreated fabrics preserved antibacterial activity against S. aureus after five washing cycles, while antibacterial activity against E. coli was preserved only after one washing cycle in the case NCS + Zn functionalized pretreated viscose fabrics. © 2021 by the authors.

AB  - In this investigation, the possibility of wood waste (hardwoods such as oaks’ and alternatives’ staves from Balkan cooperage) revalorization for simultaneous cadmium removal and wastewater disinfection was examined. All samples were characterized in terms of their crystallinity index and crystallite size, amount of functional groups, and surface chemistry (determined by ATR-FTIR) as well as antibacterial activity. Mulberry is characterized by the lowest crystallinity index which can be ascribed to the highest crystallite size disabling crystallite denser packaging, while myrobalan plum has about 23% lower crystallite size that enables crystallite better packaging, thus resulting in a 42.4% higher crystallinity index compared to the mulberry. All oaks have a significantly higher amount of carboxyl groups compared to the alternatives (0.23-0.28 vs. 0.12-0.19 mmol/g). The adsorption experiments revealed that with increasing the initial cadmium concentration from 15 up to 55 mg/g, samples’ adsorption capacity increases by 89-220%. The equilibrium data fit well with the Langmuir isotherm model implying monolayer coverage of cadmium ions over a homogeneous wood surface. The relationship between the samples’ maximum adsorption capacities (ranged from 5.726 to 12.618 mg/g), their crystallinity index, and crystallite size was established. According to ATR-FTIR spectra, aldehyde, carboxyl, hydroxyl, and phenyl groups present on the wood waste surface are involved in Cd2+ adsorption which proceeds via the interplay of the complexation, cation-π interactions, and ion-exchange mechanisms. Mulberry and myrobalan plum showed about 89% and 80% of the total uptake capacity of cadmium within 60 min, while the equilibrium was attained after 240 min of contact time. Good compliance with pseudo-second kinetic order indicated that cadmium adsorption was mediated by chemical forces. Thermodynamic parameters revealed the spontaneous and exothermic character of cadmium ion adsorption onto mulberry and myrobalan plum. All studied samples provide maximum bacterial reduction (>99%) for E. coli and S. aureus. Wood waste from Balkan cooperage can be successfully used for simultaneous cadmium removal and wastewater disinfection.

AB  - The objective of this investigation was to obtain jute fabrics with enhanced sorption properties (by using simple and cost-effective alkali and oxidative modifications) and a long life cycle. The applied alkali modifications lead to hemicellulose removal and decreased the fibers’ crystallinity, both contributing to enhanced fibers’ sorption properties, i.e., water retention power and degree of fibers’ swelling up to 49 % and 70 %, respectively. A connection between cellulose polymorphs’ (cellulose I and cellulose II) contents (determined by XRD), fibers’ surface morphology (verified by FESEM), fabrics’ crimp, and capillarity of jute fabrics modified with 17.5 % NaOH was established. During the oxidative modifications, significant changes in jute fibers’ chemical composition and structure (i.e., lignin removal and more homogeneous middle lamellae) occurred which further resulted in enhanced jute fabrics’ water retention power and capillarity as well as fibers’ swelling up to 80 %, 75 %, and 54 %, compared to the raw jute, respectively. In order to move towards a circular economy and to ensure the recycling and re-use of recycled fabrics, the jute fabrics with enhanced sorption properties were evaluated as biosorbents for anthraquinone dye C. I. Acid Blue 111. The obtained results revealed that the jute fabrics’ maximum biosorption capacities for this dye ranged from 12.94 to 18.97 mg/g, while the equilibrium adsorption data were highly consistent with the Langmuir isotherm model. Moreover, based on the predicted dye pKa values, the fabric zeta potential, content of carboxyl and aldehyde groups as well as hydrogen bond intensity (determined by ATR-FTIR), a possible mechanism of the dye biosorption onto jute fabric waste was proposed.

AB  - Magnetite (MG) modified cellulose membrane (Cell-MG), obtained by reaction of 3-aminosilane and subsequently with diethylenetriaminepentaacetic acid dianhydride functionalized waste Cell fibers (Cell-NH2 and Cell-DTPA, respectively), and amino-modified diatomite was used for Azoxystrobin and Iprodione removal from water. Cell-MG membrane was structurally and morphologically characterized using FT-IR and FE-SEM techniques. The influences of operational parameters, i.e. pH, contact time, temperature, and the mass of adsorbent on adsorption and kinetics were studied in a batch system. The calculated capacities of 35.32 and 30.16 mg g-1 for Azoxystrobin and Iprodione, respectively, were obtained from non-linear Langmuir model fitting. Weber-Morris model fitting indicates the main contribution of intra-particle diffusion to overall mass transport resistance. Thermodynamic data indicate spontaneous and endothermic adsorption. The reusability of adsorbent and results from wastewater purification showed that Cell-MG could be used as general-purpose adsorbent. The adsorbent/adsorbate surface interaction was considered from the results obtained using density functional theory (DFT) and calculation of molecular electrostatic potential (MEP). Thus, a better understanding of the relation between the adsorption performances and contribution of non-specific and specific interactions to adsorption performances and design of novel adsorbent with improved properties was deduced

AB  - Two optimized methods, based on epoxy-amino reactivity of the Cellulose fibres (Cell) modified with diethylenetriamine (Cell‒DETA), (3-Glycidyloxypropyl)trimethoxysilane (Cell-Glymo), Lignin modified with epichlorohydrine (EL) and Tannic acid (TA), as an additional crosslinker, were developed for the production of the bio-renewable Cell-EL and Cell-EL-TA membranes. The influences of pH, contact time, adsorbent dose, and temperature on adsorption performances were studied by batch adsorption tests. The calculated capacities: 53.9, 99.9, 97.8 and 63.5, 115.8, 127.5 mg g−1 for Ni2+, Pb2+, Cr(VI) using Cell-EL and Cell-EL-TA, respectively, were obtained from Langmuir model fitting at 25 °C. The thermodynamic parameters indicated spontaneous and low endothermic processes. The results of the kinetic study, i.e. pseudo-second-order (PSO) and Weber-Morris (W-M), suggest an intra-particle diffusion as a rate-limiting step. The semi-empirical quantum chemical calculations aided the analysis of the non-specific and specific adsorbent/adsorbate interactions and their contribution to the overall bonding mechanism. Membrane utility was confirmed by performing a bed column study. In general, three main environmental issues of the present study, biodegradability of the used membrane, desorption efficiency, and development of the technology for the effective effluent water treatment and safe disposal of by-products highly conform to the demand of integrated environmental management system applicability in practice.
