AB  - The status of essential and toxic trace elements in patients with different stages of chronic kidney disease (CKD) is still
unclear and not well characterized. The present study examined the circulatory levels of a wide panel of trace elements (Al,
Cr, Mn, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Cd, Pb, and U) in hemodialysis patients (HD group) and pre-dialysis patients with
stage 3 CKD (PD group). Comparisons were made between groups of patients and healthy individuals from the control group
(CG). The levels of Al, Mn, Co, Ni, Cu, As, Se, Sr, and Pb were higher, while the levels of Cr, Zn, Rb, Cd, and U were lower
in HD patients than in our CG. Higher levels of Al and Se, as well as lower levels of As, Sr, Zn, Rb, and U were significant
and distinguished HD from PD. Among other analyzed elements, Co, Se, and U are the only trace elements that did not
distinguish PD from CG at a statistically significant level. The HD group had lower serum U levels than the PD group, and
this could be a result of hemodialysis. This study also revealed that the Cu/Zn ratio could be used as a marker for early and
late detection of renal failure. Marked changes of essential and toxic trace element levels in sera indicate additional pathophysiological
events in CKD, which could additionally contribute to the preexisting increased morbidity of HD patients.
Measurement of trace elements in HD patients should be performed routinely.

AB  - Background: Although essential trace elements (ETEs) play pivotal roles in life-supporting biochemical processes, their function in innate and adaptive immunity has not been fully elucidated, particularly during immunization. Furthermore, the association between anti-SARS-CoV-2 specific IgG antibodies and ETE levels with vaccine responsiveness has not been investigated. Methods: The present study explored the status of ETEs (Mn, Cu, Zn, and Se) in sera of healthy women before and after vaccination with the anti-SARS-CoV-2 BNT162b2 mRNA vaccine in a follow-up period of six months. The main aim was to explore links between ETE levels and IgG antibodies produced against Spike glycoprotein's Receptor-Binding Domain (RBD). Results: A recombinant protein of SARS-CoV-2 comprising the receptor binding domain was successfully expressed in HEK-293 T cells. The purified protein was suitable for producing a sensitive antibody detection assay for human serum and monitored seropositivity, indicating a transient response with peak anti-SARS-CoV-2 IgG levels 2 months after vaccination. In parallel to increasing antibody titers, serum concentrations of Cu, Mn, and Se were not affected by vaccination, and concentrations remained relatively constant at the different sampling times during the 6-month observation period. Total serum Zn concentrations were slightly elevated when compared between the first and last sampling dates. Overall, no consistent effects of vaccination on any of the three trace elements analyzed in our study were observed. Conclusion: Vaccination of adult healthy female volunteers with an mRNA vaccine was not associated with consistent changes in serum trace element concentrations over a six-month observation period.

AB  - Progressive industrialization in recent decades has contributed to the increase of metal levels in the environment, which has a dangerous impact on human health, primarily pregnant women. In this study, we aimed to compare levels of various elements in maternal and umbilical cord (UC) plasma samples collected from 125 healthy pregnant women, conduct correlation analysis among paired plasma samples, and compare our data with other populations worldwide. The study design included the following elements: essential (Mn, Co, Cu, Zn, Se, Mo), non-essential (Be, Al, Ni, As, Rb, Sr, Cd, Sb, Pb, U), rare earth (La, Pr, Ce, Nd, Sm, Eu, Gd, Dy, Ho, Er), and noble metals (Ru, Rh, Re, Pt). Levels of 30 elements were higher in maternal plasma than in UC plasma samples. However, no disparities at the statistically significant level were found for Be, Zn, Rb, Cd, Ce, and Ho. Correlation analysis among paired plasma samples revealed only positive/synergistic correlations of different strengths between most elements. Compared to other countries across the globe, our participants had considerably lower plasma levels of Zn and higher levels of Co, Ni, and As. This study provides not only a new and deeper comprehension, but also the first insight into the levels, correlation, distribution, and potential transplacental transfer of 30 elements.

AB  - Compounds used in the fashion industry effect the water bodies in the vicinity of textile factories, resulting in the visible coloration of surface water. Fe-doped graphite-based in house prepared electrodes were used in the Fenton--like degradation of Reactive Blue 52 (RB52). The electrodes consisting of high-density graphite in three granulation sizes and three levels of Fe content were characterized using scanning electron microscopy (SEM). The amount of Fe in the electrodes and H2O2 concentration in syn­thetic textile wastewater were optimized. Additionally, the size of graphite grains was varied to inves­tigate whether it effects the degradation rate. Under only 10 min of electro-Fen­ton degradation, a system with 10 mmol dm-3 of H2O2 and an electrode made of 7 % of Fe and 70 µm of granulation size of graphite, degraded over 75 % of RB52, and over 99 % after 40 min of treatment. The obtained results indicate that the proposed approach could be beneficial in the field of novel materials for environmental applic­ation and that in house prepared carbon could be an excellent replacement for commercially available supports.

AB  - A series of novel polyurethane network/organoclay nanocomposites (PUN-NCs) with different soft segment contents (30–60 wt%) was prepared by in situ polymerization in solution and characterized. PU network (PUN) was made from poly(dimethylsiloxane)-based macrodiol as the soft segment and 4,4′-methylenediphenyldiisocyanate and hyperbranched polyester of the third pseudo generation as the hard segment. Nanocomposites were obtained by dispersion of organically modified montmorillonite (Cloisite 30B) nanofiller (0.5 wt%). The influence of the soft segment content on the functional properties of PUN-NCs was studied by Fourier transform infrared (FTIR), small-angle and near wide-angle X-ray scattering (SWAXS), thermogravimetric analysis (TGA), dynamic mechanical thermal analyses (DMTA), differential scanning calorimetry (DSC), nanoindentation, atomic force microscopy (AFM), scanning electron microscopy (SEM), and swelling behavior, water absorption and contact angle measurements. The biodegradation process was evaluated using mixed cultures of microorganisms that originated from soil. Mechanically strong PUN-NC materials in the form of films were obtained, pointing to good dispersion and the existence of exfoliated morphology of Cloisite 30B within the PUN matrix, and the nanocomposites with the abovementioned characteristics were obtained as a function of the soft segment content. The decrease of the soft segment content induced a higher degree of phase separated microstructure, increase of Young's modulus, hardness, plasticity, storage modulus, glass transition temperature, surface free energy and swelling ability in tetrahydrofuran, but at the same time, it is responsible for the decrease of crosslinking density and hydrophobicity of PUN-NCs. By choosing adequate soft segment content, the prepared materials can potentially be designed for coating applications, such as top coating materials in environmental conditions.

AB  - The problem of wastewater has long been ubiquitous and has great consequences for the environment and its inhabitants. Microbial fuel cells (MFCs) have enormous potential for the treatment of wastewaters polluted with azo dyes. The amount of energy that can be produced from a single-chamber MFC is sufficient to perform decolorization and degradation of such dyes, which are widely used in the textile industry. This study on the azo dye, reactive black 5 (RB5), provides an alternative method through three parallel-connected MFCs to obtain electricity that directly serves for the dye’s electrochemical degradation. We examined degradation followed by decolorization of RB5 using Fe and Pt electrodes, together with H2O2, to achieve the electro-Fenton process. The amount of voltage produced (295 mV), the current density (276 mA m−3) and the power density (50 mW m−3) were sufficient to degrade 25 mg L-1 RB5 dye with 0.5 mM H2O2 in just 2 h. The dye degradation mechanism was investigated using UV–VIS, FT-IR and HPLC-MS/MS. The ecotoxicity of the degradation products was assessed using a bacterial model, Aliivibrio fischeri. These tests showed that there was successful degradation of the dye to products whose toxicity is less than that of RB5.

AB  - According to recent research, even low levels of environmental chemicals, particularly heavy metals, can considerably disrupt placental homeostasis. This review aims to explore the profile of non-essential trace metals in placental tissues across the globe and to specify trace metal(s) that can be candidates for impaired placental health. Accordingly, we conducted an extensive survey on relevant databases of peer-reviewed papers published in the last two decades. Among a considerable number of non-essential trace metals, arsenic (As), lead (Pb), cadmium (Cd), and mercury (Hg) were identified as the most detrimental to placental health. Comparative analysis showed remarkable differences in placental levels of these trace metals worldwide. Based on current data reported across the globe, a median (min–max) range from 0.55 to 15 ng/g for placental As levels could be deemed safe. The placental Cd and Pb levels were markedly higher in smokers than in non-smokers. Occupationally exposed pregnant women had several orders of magnitude higher Cd, Pb, and Hg levels in placental tissues than non-occupationally exposed women. Also, we concluded that even low-level exposure to As, Cd, Pb, and Hg could be deleterious to proper fetal development. This review implies the need to reduce exposure to non-essential trace metals to preserve placental health and prevent numerous poor pregnancy outcomes. Overall, the information presented is expected to help plan future fundamental and applied investigations on the placental toxicity of As, Cd, Pb, and Hg. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

AB  - In this work hydrogen production activity of a series of the nickel-loaded, nitrogen-doped titanate-based photocatalysts was tested by water splitting reaction in isopropanol-water mixture. The utilization of ammonium ions during catalyst synthesis and subsequent calcination led to successful formation of nitrogen-doped nanotubular titanates with lower sodium content, favored titanate-to-anatase transformation and enhanced textural, morphological and interface properties. The photocatalytic tests revealed that hydrogen production activity of nitrogen-doped titanates is ten times higher compared to nitrogen-free titanates. The presence of highly photoactive anatase phase, improved anatase crystallinity and lower amount of sodium ions are found to be decisive factors for increased hydrogen production activity. The optimal nickel loading was determined and the variation in photocatalytic activity with reduction temperature was explained. Stability tests gave quantitative analysis of the effects of reaction products accumulation and photocorrosion on the catalyst deactivation.

AB  - Due to the recognized harmful effects of some trace elements on fetal development after long-term exposures, it is first important to address their basic/physiological levels before monitoring toxicological effects and clinical outcomes on prenatal and postnatal health. This research aimed to define, for the first time, reference values for multiple (ultra) trace elements in umbilical cord blood (UCB) plasma samples of a notable number of healthy pregnant women (n = 125). All samples were collected during 2020–2021 and all participants were from Belgrade and two regions (Šumadija and Podunavlje). Following trace elements were enrolled in this study: essential (Mn, Co, Cu, Zn, Se, Mo), toxic (Be, Al, Ni, As, Rb, Sr, Ag, Cd, Sb, Ba, Tl, Pb, Th, U), rare earth (La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm), and noble metals (Ru, Rh, Pd, Re, Ir, Os, Pt). UCB plasma samples were diluted with suitable solvents and analyzed by inductively coupled plasma-mass spectrometry. The analytical technique used was validated by the standard addition method and using certified reference materials. Zn was found in the highest amount and Tm in the least amount. Be, Co, Ag, Sb, La, and Ce exhibited statistically significant differences in the four age groups (20 to 41 years), whereas Ag and Ce showed a tendency to increase with age. Furthermore, our participants had notably higher As, Ni, and Co, levels and lower Zn levels compared to other populations. This is the first study that, in addition to analyzing essential and toxic trace elements, also provided an analysis of noble and rare earth elements in UCB plasma samples. Presented results can be used as a starting point or database for further studies, in terms of predicting the pregnancy outcome and postnatal development.

AB  - The osmotic dehydration (OD) of celery root in sugar beet molasses was studied at three temperatures (20, 35, and 50 °C) and three immersion periods (1, 3, and 5 h) in order to examine the changes in antioxidant potential and phenolic profile of celery root throughout the process. The antioxidant capacity (AOC) of dehydrated samples was evaluated by spectrophotometric and polarographic assays, the total phenolic content by the Folin-Ciocalteu method, and the individual phenolic compounds by HPLC-DAD. As a result of OD in molasses, the AOC and phenols content in samples increased proportionally to the augmentation of temperature and the immersion time. Vanillic acid, syringic acid, and catechin were detected in dehydrated samples as a result of transfer from molasses. Compared to fresh celery root, the content of identified phenols in osmodehydrated samples was improved from 1.5 to 6.2 times. Strong correlations between applied assays were obtained, except for the DPPH. Based on the correlation analysis chlorogenic acid, gallic acid, chrysin, catechin, and kaempferol showed the greatest contribution to the overall AOC of osmodehydrated celery root. Molasses, an agro-industrial waste from sugar production, could be valorized as a valuable osmotic solution.

AB  - With the ever-growing concern for human health and wellbeing, the prenatal period ofdevelopment requires special attention since fetuses can be exposed to various metals through themother. Therefore, this study explored the status of selected toxic (Pb, Cd, Ni, As, Pt, Ce, Rb, Sr, U)and essential trace metals (Mn, Co, Cu, Zn, Se) in the umbilical cord (UC) sera, maternal sera, andplacental tissue samples of 92 healthy women with normal pregnancies. A further aim focuses on thepotential transplacental transfer of these trace metals. Based on the obtained levels of investigatedelements in clinical samples, it was observed that all of the trace metals cross the placental barrierand reach the fetus. Furthermore, statistical analysis revealed significant differences in levels oftoxic Ni, As, Cd, U, Sr, Rb, and essential Mn, Cu, and Zn between all three types of analyzed clinicalsamples. Correlation analysis highlighted As to be an element with levels that differed significantlybetween all tested samples. Principal component analysis (PCA) was used to enhance these findings.PCA demonstrated that Cd, Mn, Zn, Rb, Ce, U, and Sr were the most influential trace metals indistinguishing placenta from maternal and UC serum samples. As, Co, and Cu were responsible forthe clustering of maternal serum samples, and PCA demonstrated that the Pt level in UC sera wasresponsible for the clustering of these samples. Overall, the findings of this study could contribute toa better understanding of transplacental transfer of these trace metals, and shed a light on overalllevels of metal exposure in the population of healthy pregnant women and their fetuses.

AB  - Background: As a consequence of the progressive decline in human semen quality in recent decades, modern epidemiological investigations have identified several trace elements that could be responsible for this phenomenon. However, their levels in semen have not been clearly elucidated, particularly for elements present in ultra-trace levels. Methods: We aimed to determine the levels of 39 (ultra)trace elements and 5 macroelements in human semen samples with confirmed normozoospermia using ICP-based techniques. The research was amplified by analyzing blood samples from the same participants. Results: Among the analyzed (ultra)trace elements in semen samples, Zn is the most and Tm is the least prominent. Zn levels in semen are so high that Zn should be considered as a macroelement in this matrix. The levels of Zn, Rh, Sm, Re, Ir, Tl, Na, and Ca were significantly higher in semen, while the levels of Cu, As, Rb, Gd, Sb, Tb, Tm, Lu, K, and Fe were significantly higher in blood. Correlation analysis of the levels of 44 individual elements in paired semen and blood samples revealed positive correlations between 43 of the elements, particularly for Tl and Pt. An exception was the negative correlation for Cu, which showed that its high level in semen is associated with a low level in blood and contrariwise. Conclusion: The reported data can be used as baseline levels/reference values for 44 elements in human semen. Furthermore, the findings of this study could be relevant for further consideration of male infertility.

AB  - Honokiol is neolignan present in the magnolia bark. It displays versatile pharmacological properties—neuroprotective and anxiolytic effect, anti-cancer activity and antimicrobial effect being the most important. This paper aims to develop a voltammetric non-enzymatic biosensor for honokiol detection, quantification and monitoring in drugs and cosmetic products. The materials used in this study were synthesized and characterized by HR-XRPD, SEM, ATR-FTIR and electrochemical methods. Bi2O3, being a p-type semiconductor, was used as an electrode material. Both its semiconductivity and electrocatalytic properties result from lattice structure defects, which differ on the surface and in the bulk of the bismuth oxide crystal, and therefore are crystal size dependent. The influence of the particle size of Bi2O3 on its electrocatalytic properties was studied, and it was confirmed that Bi2O3 nanoparticles have better overall conductive/resistive and catalytic characteristics than microribbons and that the optimal electrode modification for sensing application was obtained by Bi2O3@SWCNT composite material preparation. Here, we established a sensitive electrochemical sensing platform for honokiol detection based on CP electrode modified with bismuth oxide nanoparticles and SWCNT with the 0.17 μM limit of detection, and linear operating range from 0.1 to 50 μM. The effect of potential interferents on honokiol detection was explored. Obtained results in the interference tests and the real sample analysis suggest that the developed approach is selective, accurate and reproducible. Due to the low detection limit and a wide working range, the proposed sensing platform opens great opportunities for further construction of sensors for honokiol detection and monitoring in the pharmaceutical industry and medicinal chemistry.

AB  - Pheochromocytoma (PCC) is an unusual benign adrenal tumor with an unexamined status of the elements. This study delivers the first insight into the levels of microelements (Mn, Co, Cu, Zn, As, Se, Th), toxic elements (Cd, Pb, U), and macroelements (Na, K, Mg, Ca) in both adrenal tissue and whole blood samples collected from PCC patients. The results were strengthened by comparing recorded findings with the patients’ healthy adrenal tissue (HAT) and with whole blood samples from the healthy individuals. PCCs had significantly higher levels of Zn, Se, Na, K, and Mg and lower levels of Mn, Co, Pb, and As than that of HATs. Compared to healthy blood samples, the patients’ blood exhibited considerably higher levels of Na, K, and Ca but significantly lower levels of Mn, Cu, Zn, Se, and Mg. Females had significantly higher levels of essential Se and toxic Pb and Cd in their PCC tissue samples compared to males. PCC tissue levels of Mn and Cu were significantly elevated in smokers over levels in nonsmokers and in PCC patients with tumor sizes below 5 cm compared to PCC diameters above 5 cm. The data presented in this study provide a new insight into the pathophysiology of PCC. Thus, recorded elements should be considered as initiators/modifiers of PCC and potential inductors of malignant transformation. The findings of this research deepen scientific understanding of this rare adrenal disease, which, in turn, could highlight the pathogenesis of PCC.

AB  - There are only a few reports examining the impact of oxidative stress in patients with benign andmalignant brain tumors. In this study we investigated whether there are changes in antioxidantsystem (AOS) parameters and key trace elements between control, benign and malignant braintissues. The study also aimed to examine correlations between the analyzed parameters. The studyenrolled both types of brain tumors, benign tumors (BT) and malignant tumors (MT). The resultswere compared with control tissue (CT) without tumor infiltration collected from patients with BT.The following antioxidant parameters were determined: activities of total, manganese‑containing,and copper/zinc‑containing superoxide dismutase (TotSOD, MnSOD and CuZnSOD), activities ofcatalase, glutathione peroxidase, glutathione S‑transferase, glutathione reductase and acetylcholineesterase (AChE), the concentrations of glutathione and sulfhydryl groups and of manganese (Mn),copper (Cu), zinc (Zn), and selenium (Se). BT and MT had altered activities/levels of multiple AOSparameters as compared to CT, indicating that tumor cells had an altered cell metabolism and changesin AOS represent adaptive response to increased oxidative stress. Low MnSOD and AChE and highGST activities were significant for distinguishing between MT and CT. Malignant tissue was alsocharacterized by lower Mn and Cu concentrations relative to CT and BT. Principal Component Analysisclearly discriminated BT from CT and MT (PC1, 66.97%), while PC2 clearly discriminated CT from BTand MT (33.03%). Most correlative relationships were associated with Se in the BT group and Cu in theMT group. The results of this study reveal differences between the AOS parameters and the essentialtrace elements between the analyzed groups. The observed dysregulations show that oxidative stresscould have an important role in disrupting brain homeostasis and its presence in the pathogenesis ofbenign and malignant brain tumors.

AB  - Modest progress has been made in understanding the role of trace elements as endocrine disruptors. The aim of this study was to examine whether there is a change in the content of trace elements in thyroid disease, as well as whether the ratio of elements could be considered a blood marker for thyroid disease. In addition, this study examined the influence of biological and clinical/pathological parameters on the elemental profile. Blood samples from patients diagnosed with multinodular goiter (MNG), thyroid adenoma (TA), and thyroid cancer (TC) were examined and compared with control samples using chemometric analysis. The concentrations of essential (Mn, Co, Cu, Zn, Se) and toxic elements (Ni, As, Cd, Pb, U) were determined by ICP-MS. This study showed for the first time that the content of Mn, Co, Ni, Cu, Zn, Se, and Pb in pathological blood samples was significantly lower compared to the control, while opposite results were obtained for As, Cd, and U. Based on the classification model, the most important trace metals for discrimination of MNG and TC from the control group (CG) were Co and Zn, while Co, Zn, and Mn influenced the distinction of CG from TA. Moreover, it was found that Cu/Zn and U/Se ratios had significantly increased values in pathological blood samples leading to the possibility of establishing new circulating screening markers. These findings can represent significant translational information since these diseases are widespread and the diagnostic procedure is still difficult in many cases.

AB  - Background
The baseline status of trace metals in adrenal tissue is unresolved, while the elemental profile for any adrenal pathology has not been examined so far. This study aimed to determine the baseline status of important toxic (Ni, As, Cd, Pb, Th, U) and essential trace elements (Mn, Co, Cu, Zn, Se) in healthy adrenal tissues (HATs) as well as to examine whether there are alterations in the elemental composition of adenomatous adrenal tissues (AATs). Furthermore, this study aimed to find potential trace metals that could play a role in the pathogenesis of adrenal adenoma (AA).

Methods
The study included 45 patients diagnosed with AA. Impacts of relevant parameters such as gender, age, smoking habits and nodular sizes were considered. All samples were subjected to microwave digestion and the trace elements were determined by inductively coupled plasma mass spectrometry (ICP-MS).

Results
This is the first study that provided an insight into the elemental status of HATs. It was also shown that AATs had altered trace metal contents. Compared to HATs, the most significant findings were related to the high content of essential (Cu, Mn, Se, Zn) and Pb as a non-essential metal. Although gender, age and smoking habits had a modest effect on metal profiles, the most significant alterations were related to the nodular diameter above 4 cm, indicating that the growth of benign tumor could influence changes in elemental composition.

Conclusion
For the first time the baseline contents of essential and toxic trace metals in HATs were determined. The results of this study may highlight the role of toxic and essential trace metals in AAs and could provide new insights into the molecular basis of pathophysiological changes caused by the hazardous effects of trace metals on adrenal structure and function.

AB  - Drinking water and wastewater treatment facilities often have a chemical oxidationstep for disinfection, the removal of organic micropollutants, color removal and taste andodor control. Among the most commonly used oxidants are chlorine dioxide (ClO2 ), chlorine, and ozone.ClO2  has been increasinglyemployed as disinfectant in water treatment due to its antibacterial and antiviral properties. As a powerful oxidant, ClO2  can remove many organic and inorganic pollutants [1,2]. The aim of the present study was to assess thepotential of ClO2  to oxidize pharmaceutical during water treatment. Therefore, degradation of ibuprofen (IBP) using ClO2 in water was investigated.The degradation under different reaction conditions (concentration of ClO2 : 5, 10, 15 mg/L; concentration of ibuprofen: 10, 20, 35, 60 mg/L; reaction time: from 0.5 to 24 h; pH values: 3, 7, 10) was monitored using high performance liquid chromatography (HPLC) analysis, while mineralization degree was detemined by total organic carbon (TOC) measurements. The highest degree of IBPdegradation in deionized water was obtained by treatment with 15 mg/L ClO2 , using 10 mg/L ibuprofen, at pH = 10, after 24 h of treatment. The obtained degradation degree value under optimal conditions was 99%. TOC analysis of ibuprofen showed reduction in content of organic carbon in the solution. Before degradation TOC content was 7.8 mg/L and after 5.6 mg/L. This showes that degradation and mineralization of ibuprofen occur during this process. The degradation products obtained under optimal conditions were analyzed and confirmed by gas chromatography–mass spectra (GC–MS) and the reaction pathwayswere proposed.From GC chromatograms, degradation products of ibuprofen appeared at following retention times: 4.35 min, 5.12 min, 6.76 min, and 7.05 min. After the analysis of mass spectra, based on the spectral characteristics and the ratio of mass and charge (m/z), it was determined that there are four main degradation products of ibuprofen, after treatment with ClO2.The first characteristic ion appeared at 6.76 min and has m/z 163 (2-(4-methylphenyl) propionic acid). In further degradation path, two products are formed, one of which is a characteristic ion with m/z 57 (2-methylpropane) at 4.36 min, while the other product is further decomposed to give two new products, one of which is also a characteristic ion with m/z 57 (acetic acid) at 5.21 min. Another characteristic ion having m/z 161 (1-ethyl-4-isobutylbenzene) appeared at 7.05 min. ClO2 treatment is an efficient method for IBP degradation.The findings of the present study are very useful for the treatment of drinking waters contaminated with pharmaceutical.

AB  - The textile industry is one of the major pollutants of waterbodies with effluents high in biochemical and chemical oxygen demand values, high values of total dissolved solids, total suspended solids, and low dissolved oxygen values along with strong color. The existence of a successful method for its decontamination would be beneficial. In this work, we synthesized sponge-like europium oxide (Eu2O3) using a template-directed route from carbon hollow spheres, obtained from glucose as a carbon source. The material synthesis method was done in an aqueous environment, without using any organic solvents. Electrochemical properties of the synthesized material were investigated using cyclic voltammetry and electrical impedance spectroscopy, while morphological characterization was done using scanning electron microscopy and X-ray powder diffraction analysis. Eu2O3 were successfully immobilized at the surface of a screen-printed carbon electrode (Eu2O3/SPCE) using the drop-casting method. Finally, the prepared electrodes were tested toward the removal of Reactive Blue 52 (RB52) using electrochemical advanced oxidation processes (EAOPs). Important parameters, that is, the supporting electrolyte, its concentration, pH value, and the applied voltage, were optimized for RB52 degradation. The rate of removal was monitored spectrophotometrically and by high-performance liquid chromatography with a diode array detector (HPLC-DAD). It was found that the proposed approach reaches complete decolorization of the RB52 solution after a 60-min treatment, at pH 5.6 of KCl supporting electrolyte at a concentration of 0.05 M. Under optimal parameters, after 3 h of treatment, total organic carbon (TOC) was lowered by ~40%. The obtained results indicate that the proposed method may find potential application in EAOPs, considering electrode stability, durability, and efficiency and simplicity of the method.

abstract = "The textile industry is one of the major pollutants of waterbodies with effluents high in biochemical and chemical oxygen demand values, high values of total dissolved solids, total suspended solids, and low dissolved oxygen values along with strong color. The existence of a successful method for its decontamination would be beneficial. In this work, we synthesized sponge-like europium oxide (Eu2O3) using a template-directed route from carbon hollow spheres, obtained from glucose as a carbon source. The material synthesis method was done in an aqueous environment, without using any organic solvents. Electrochemical properties of the synthesized material were investigated using cyclic voltammetry and electrical impedance spectroscopy, while morphological characterization was done using scanning electron microscopy and X-ray powder diffraction analysis. Eu2O3 were successfully immobilized at the surface of a screen-printed carbon electrode (Eu2O3/SPCE) using the drop-casting method. Finally, the prepared electrodes were tested toward the removal of Reactive Blue 52 (RB52) using electrochemical advanced oxidation processes (EAOPs). Important parameters, that is, the supporting electrolyte, its concentration, pH value, and the applied voltage, were optimized for RB52 degradation.

AB  - The first series of polyurethane network nanocomposites (PUNN) was prepared by in situ polymerization [1,2] from poly(dimethylsiloxane)-based prepolymer as the soft segment and 4,4’-methylene diphenyldiisocyanate and hyperbranched polyester of the third pseudo generation as the hard segment, in the presence of organically modified montmorillonite nanofiller (Cloisite 30B; 0.5 wt.%). The second series of pure polyurethane networks (PUN) without organoclay was also prepared. The composition of prepared materials in both series was varied through variation of soft segment content from 30 to 60 wt.%. Biodegradability of prepared materials was measured using mixed cultures of microorganisms that originated from soil. This test used soil bacteria and fungi to assess the impact of the environment on polymer compounds. This test is intended to determine which polymer compositions are best suited for coating other materials that must endure lengthy exposure to harsh environmental conditions while retaining their principal functionalities. The biodegradation test was performed under aerobic conditions in the dark condition and in a thermostat at 28 °C. Bacterial and fungal mixed cultures were alternated monthly. After 3 and 6 months of the test, the materials were washed with water, dried in a vacuum oven to constant weight, and used for gravimetric measurements of weight loss. The prepared materials before and after biodegradation test were characterized by FTIR spectroscopy. The results showed that pure PUNs (18.35-18.66 wt.% after six months) possess the highest weight loss as compared to PUNNs (from 7.53 to 14.78 wt.% after six months) after incubation of up to six months. PUNN films had lower biodegradation degree as compared the pure PUN films. Biodegradability was lower for materials with lower soft segment content. In FTIR spectra of PUNN after biodegradation differences were noted at approximately 1700-1735 and 3324 cm-1. The structures contributing to strong hydrogen bonds were partially destroyed during the biodegradation process. The results showed that PUNN with 40 wt.% of soft segment (PUNN-40) is the most resistance material to biodegradation. The reason was probably due to more hydrogen bonding between the polymer and Cloisite 30B organoclay and its better mechanical properties of PUNN-40 sample as compared to other prepared PUNN materials. The obtained materials are good candidate as top coating materials exposed to the environmental conditions.
