Pyrite-activated persulfate for simultaneous 2,4-DCP oxidation and Cr(VI) reduction

Peng He et al.

Summary: Organic pollutants and heavy metals in wastewater were effectively removed simultaneously using pyrite and persulfate system, where SO4 center dot- and (OH)-O-center dot radicals were identified as the oxidative species responsible for degrading 2,4-DCP. Pyrite acted as a catalyst for Cr(VI) reduction, with Fe identified as the main catalytic site, showcasing a new strategy for the simultaneous removal of heavy metals and organic compounds in wastewater treatment.

Synergistic activation of persulfate by natural chalcocite and ferrous ions by promoting the cycling of Fe3+/Fe2+ couple for degradation of organic pollutants

Guang-En Yuan et al.

Summary: This study demonstrated that natural chalcocite can serve as an efficient co-catalyst for the activation of persulfate in degrading organic contaminants. The synergistic effect between NCC and Fe2+ in catalyzing PS for degradation of orange G was identified. Parameters such as NCC dose, Fe2+ concentration, initial pH, and the presence of anions were found to have important impacts on OG degradation. NCC showed good reusability in synergistic activation of PS with Fe2+ for OG degradation over five cycles.

Activation of peroxymonosulfate by natural molybdenite for dye degradation: Identification of reactive species and catalytic mechanism

Guang-En Yuan et al.

Summary: This study used natural molybdenite to activate peroxymonosulfate for the removal of organic contaminants effectively. The degradation rate increased with higher temperature, catalyst, and PMS dosages, while initial pH had little effect on the system. Reactive oxygen species played a key role in the degradation process in the MDN/PMS system.

Critical review of reductant-enhanced peroxide activation processes: Trade-off between accelerated Fe3+/Fe2+ cycle and quenching reactions

Hongyu Zhou et al.

Summary: This review systematically summarized the origins, development, basic mechanism, and limits of reductant-enhanced iron-based peroxide activation processes. It was found that the use of reductants could accelerate the reduction of Fe3+ and quench the production of reactive species, with the trade-off determined by intrinsic chemical properties and experimental conditions. Additionally, practical application potential of different reductants based on toxicity, costs, and self-transformation products was evaluated, and new enhancement strategies were proposed for future research needs.
