Summary: In this study, a Fe-Mn-Zr ternary magnetic sorbent was synthesized for efficient removal of both inorganic and organic arsenic species. The optimized sorbent showed higher adsorption capacity and the adsorption performance was affected by pH, contact time, and the presence of other anions in water. The mechanism study indicated that ion exchange and complexation were key processes in arsenic removal.

Summary: In this study, Fe-Cu binary oxide loaded on zeolite (Fe/Cu/zeolite) was used as a heterogeneous Fenton catalyst for the catalytic degradation of carbamazepine (CBZ) at near-neutral pH. The Fe/Cu/zeolite catalyst exhibited excellent performance in degrading CBZ, achieving complete degradation at initial pH values ranging from 3 to 7 and maintaining a removal efficiency above 74% even at pH near 10. After repeated use, the Fe/Cu/zeolite catalyst still showed over 95% removal efficiency of CBZ. The main active oxidants were identified as hydroxyl radicals (•OH) based on quenching experiments and ESR testing. XPS analysis revealed that the high catalytic efficiency was attributed to the synergistic effect of Fe(III)/Fe(II) and Cu(II)/Cu(I) redox cycles. Therefore, this catalyst can be effectively used for the degradation of organic pollutants in heterogeneous Fenton systems.

Summary: The study reveals that both HO center dot and [(FeO)-O-IV](2+)/ Fe-III(O2H) are concurrently produced on the surface in the acidic to near-neutral pH range, but HO center dot is the major oxidant responsible for substrate oxidation. As pH increases, the yield of both oxidants is inhibited by the decreasing availability of surface sites due to ferrihydrite particle aggregation.

Summary: Biochar loaded with manganese and iron showed excellent catalytic ozonation activity, effectively removing atrazine with hydroxyl radicals as the main oxidant. The enhanced adsorption and decomposition of O-3 on the loaded biochar led to improved degradation pathways of atrazine, reducing toxicity of oxidation products significantly. This research indicates the great potential of Mn-loaded and Fe-loaded biochar for heterogeneous catalytic ozonation in water pollution treatment.
