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.

Abstract With maximum utilization of active metal sites, more and researchers have reported using single atom catalysts (SACs) to activate persulfate (PS) for organic pollutants removal. In SACs, atoms (Fe, Co, Cu, Mn, etc.) different substrates (porous carbon, biochar, graphene oxide, carbon nitride, MOF, MoS 2 , others) are the basic structural. Metal atoms, substances, connected chemical bonds all a great influence on electronic structures that directly affect activation process PS degradation efficiency pollutants. However, there few relevant reviews about interaction between substances during process. this review, SACs with species summarized investigate metal−support evaluate their effects oxidation reaction Furthermore, how reactive pathways also discussed. Finally, challenges prospects in PS‐AOPs proposed.

Limited by the detection techniques, reactive species involved in catalytic water purification processes are difficult to be clarified. Spin-trapping electron paramagnetic resonance (EPR) analysis is recognized as a reliable tool for radical identification, which 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) usually used trapper. However, it questioned that of adducts DMPO definitively indicates generation radicals. In this work, transformation caused transition metal oxides monitored EPR, and abundant spin signals observed. MnO2, Mn2O3, NiO could oxidize into DMPOX through direct oxygen transfer. Besides, dissolved ions transform misleading DMPO–OH DMPO–R. The findings e.g., interactions between different quenching behavior pathways, would help with identifications both engineered systems natural environments.

Advanced oxidation processes (AOPs) are rapidly evolving but still lack well-established protocols for reliably identifying oxidative reactive species (ORSs). This Perspective presents both the radical and nonradical ORSs that have been identified or proposed, along with extensive controversies surrounding mechanisms. Conventional identification tools, such as quenchers, probes, spin trappers, might be inadequate analytical demands of systems in which multiple coexist, often yielding misleading results. Therefore, challenges these complex, short-lived, transient must fully acknowledged. Refining methods is necessary, supported by rigorous experiments innovative paradigms, particularly through kinetic analysis based on situ spectroscopic techniques multiple-probe strategies. To demystify complex ORSs, future efforts should made to develop advanced tools strategies enhance mechanism understanding. In addition, integrating real-world conditions into experimental designs will establish a reliable framework fundamental studies, providing more accurate insights effectively guiding design AOPs.
