Urbanization and industrialization have exerted significant adverse effects on water quality, resulting in a growing need for reliable eco-friendly treatment technologies. Persulfate (PS)-based advanced oxidation processes (AOPs) are emerging as viable technologies to treat challenging industrial wastewaters or remediate groundwater impacted by hazardous wastes. While the generated reactive species can degrade variety of priority organic contaminants through radical nonradical pathways, there is lack systematic in-depth comparison these pathways practical implementation different scenarios. Our comparative analysis reaction rate constants vs. indicates that radical-based AOPs may achieve high removal efficiency with relatively short contact time. Nonradical feature advantages minimal matrix interference complex wastewater treatments. (e.g., singlet oxygen, high-valent metals, surface activated PS) preferentially react bearing electron-donating groups, allowing enhancement degradation known target contaminants. For byproduct formation, analytical limitations computational chemistry applications also considered. Finally, we propose holistically estimated electrical energy per order (EE/O) parameter show significantly higher requirements pathways. Overall, critical comparisons help prioritize basic research PS-based inform merits system-specific applications.
