Summary: This study examined the competitive adsorption of perchlorate onto modified reed (MR) in the presence of phosphate and nitrate contaminants. The results showed that MR had a higher adsorption capacity for perchlorate alone, but the presence of phosphate had a stronger competitive effect on perchlorate adsorption. A multicomponent isotherm model was developed to describe the binary adsorption of perchlorate in the presence of competing anions.

Summary: Phosphorus control is crucial for mitigating water eutrophication and addressing the scarcity of phosphorus resources. A novel nanocomposite, HNdO-PsAX, was developed for selective removal of phosphate. It exhibited stable and efficient phosphate adsorption over a wide pH range and outperformed the commercial lanthanum-based adsorbent, Phoslock. The specific Nd-P inner-sphere complexation in HNdO-PsAX contributed to its superior affinity towards phosphate. Fixed-bed treatment showed its high capacity for treating wastewater, and the feasibility of regeneration was recognized.

Summary: The study demonstrates the modification of anion exchangers to obtain a reactive organic polymer containing dispersed CuxS. The distribution of cuprite or tenorite within the polymeric matrix and the porous structure of the anion exchanger determine the content of CuxS. The sulphidation process converts Cu2O into CuS more efficiently and selectively compared to CuO, and the morphology of the resulting covellite particles is influenced by the porous structure of the anion exchanger.

Summary: In this study, the modification of iron oxide ion exchanger Ferrix A33E with neodymium (III) ions resulted in a new material (Ferrix A33E-Nd(III)) with enhanced sorption efficiency for arsenate(V) ions. Characterization of A33E-Nd(III) was done using various techniques and the kinetic and thermodynamic parameters of arsenate(V) sorption were calculated. The Nd(III)-modified material showed a larger maximum sorption capacity, great stability, and the ability to be regenerated multiple times without significant loss of efficiency.

Summary: A bifunctional Co-doped La(OH)(3) composite with catalytic and adsorption active sites was synthesized and demonstrated excellent performance in removing As(III) from water. The Co-La/PMS system achieved nearly 100% As(III) removal within 10 minutes. The combined system showed significantly higher removal capacity and faster kinetics compared to Co-La adsorption alone. The enhanced performance was attributed to the production of reactive oxygen species and the generation of new adsorption sites. The Co-La/PMS system offers a promising approach for purifying arsenic-contaminated water.

Summary: The need for recycling used materials has become urgent due to environmental pollution and the depletion of many deposits. This paper presents a study on the use of a biodegradable complexing agent (IDHA) for the recovery of La(III), Nd(III), and Ho(III) through adsorption using different ion exchangers. The results show that Purolite S957 has the highest adsorption capacity for La(III) complexes, while Lewatit SP112 exhibits high efficiency in adsorbing Nd(III) and Ho(III) complexes.

Summary: In this study, Cu2+ ions were successfully integrated into the growth of ZIF-8 to form Cu-NC material, which served as a substrate for the deposition of palladium nanoparticles and yielded the Pd/Cu-NC catalyst. The catalytic potential of this catalyst in glycerol carbonate synthesis was superior to that of the NC carrier alone. Density functional theory simulations revealed the important role of the interaction between copper and palladium in carbonyl formation and ring closure.

Summary: In this study, a highly antimicrobial and sensorial material for high traffic surface coatings was developed. The material consists of polyvinylidene fluoride and copper core-shell nanowires, which exhibit strong antimicrobial effects against Escherichia coli and Staphylococcus epidermidis while maintaining biocompatibility with mammalian cells. The addition of copper core-shell nanowires provides antimicrobial activity and suitable mechanical and electrical characteristics for the development of an antimicrobial capacitive touch sensing matrix for interactive surfaces.

Summary: In this study, functional Zn-based mixed metal oxides (Zn-MMOs) were fabricated using a ZnO-assisted hydrothermal coprecipitation method with spent metal ions from acid-leached clay for antibiotic and microorganism removal from water. The results demonstrated that the composition, micro-structure, adsorption, and antibacterial activity of Zn-MMOs were influenced by the amount of ZnO added. Zn-MMOs showed high adsorption capabilities for tetracycline and chlortetracycline, as well as comparable antibacterial activity to commercial ZnO, making them effective for eliminating microbial contaminants in water. This work offers a collaborative solution for waste resource utilization and wastewater pollution treatment, contributing to the promotion of green economy and sustainable development.

Summary: The synthesis of copper compounds with polymeric adsorbents showed that Cu2O and CuO significantly reduced the porosity of the obtained composites. Samples dried thermally lost porosity and increased bulk density, while freeze-dried samples retained typical macroporous characteristics. This reduction in porosity was mainly caused by the surface morphology and agglomeration tendency of Cu2O and CuO particles.
