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  - An optimal laboratory two-step procedure was developed for sodium/potassium O-alkyl
carbonodithioate (sodium/potassium alkyl xanthates) production in the form of aqueous solutions.
Sodium isopropyl xanthate (Na-iPrX), as the most effective salt in a real ore flotation process, was
also produced at an industrial level and introduced as a collector for copper ores. In order to reduce
toxicity of the flotation process and improve sustainability by minimising environmental impacts,
collector efficiency and selectivity in the flotation process were studied in relation to possible synergism
of xanthates combined with the derived biomass and biodegradable green reagents levulinic acid,
5-hydroxymethyl-2-furanacrylic acid (HMFA), and condensation product of hydroxymethylfurfural
and levulinic acid. Optimal content of 30% of HMFA in the collector pointed to the possibility of
substitution of commercial xanthate collector without significantly affecting its efficiency/selectivity.
The density functional theory (DFT) calculations provided insights into the interaction mechanism
of Na-iPrX and HMFA with cooper. The benefits of the presented method highlight production
simplicity, mild reaction conditions, high purity and yield of products, no by-products, and
technological applicability on an industrial scale.
