Persulfate (PS)-based advanced oxidation processes (AOPs) for pollutant removal have attracted extensive interest, but some controversies about the identification of reactive species were usually observed. This critical review aims to comprehensively introduce basic concepts and rectify cognitive biases appeals pay more attention experimental details in PS-AOPs, so as accurately explore reaction mechanisms. The scientifically summarizes character, generation, different species. It then highlights complexities analysis electron paramagnetic resonance, uncertainties use probes scavengers, necessities determination scavenger concentration. importance choice buffer solution, operating mode, terminator, filter membrane is also emphasized. Finally, we discuss current challenges future perspectives alleviate misinterpretations toward mechanisms PS-AOPs.

Conventional heterogeneous Fenton-like systems employing different peroxides have been developed for water/wastewater remediation. However, a large population of consumed during various with low utilization efficiency and associated secondary contamination become the bottlenecks their actual applications. Recent strategies lowering peroxide consumptions to develop economic are primarily devoted effective radical generation subsequent high-efficiency through catalysts/systems engineering, leveraging emerging nonradical oxidation pathways higher selectivity longer life reactive intermediate, as well reactor designs promoting mass transfer decomposition improve yield radicals/nonradicals. comparative review summarizing mechanisms these has not yet published. In this review, we endeavor showcase designated achieving reduction while ensuring high catalytic activity from perspective above strategic mechanisms. An in-depth understanding aspects will help elucidate key consumption. Finally, existing problems put forward, new ideas research directions consumption proposed promote application in wastewater purification.

Imidacloprid (IMI), as an emerging pollutant, is frequently detected in pesticide wastewater. Cobalt-based single-atom catalysts (Co-SACs) doped with sulfur atoms can serve efficient strategy to activate peroxymonosulfate (PMS) and degrade organic pollutants. The paper employed density functional theory computational toxicology deeply explore the mechanism ecotoxicity of IMI when S were introduced into Co-SACs for PMS activation. result demonstrated that be preferentially decomposed SO
