“…21,24 Studies have used heat-activated persulfate to produce SO 4 À radicals, and through their oxidative properties, BA undergoes decarboxylation and hydroxylation reactions to achieve degradation. 25 In previous studies there were also degradation reactions using SO 4 À radicals and BA derivatives such as benzoate, and their reaction products were detected. 26 At night, NO 3 radicals can be used as an important oxidant to degrade atmospheric organic pollutants.…”

“…Generally, the peak area of these 14 products in PS-heat solution were relatively higher than those in PS-catalyst circumstance. Zrinyi et al (2017) in 2017 systematically investigated the effect of reaction temperature on the transformation pathway of benzoic acid oxidized by PS and the results showed product distribution indeed differed with changed temperature. They also found that SO 4 •− mainly contributed to the transformation of substrate at 70 ℃ (very approximate to 65 ℃ used in this work), whereas, •OH was considered as the dominant active species under the PS activated by N-doping single wall carbon nanotubes.…”

An in-depth study on the degradation of bisphenol S (BPS) by both single-walled carbon nanotubes and heat activated persulfate (PS) was investigated in detail. The factors like materials dosage, initial substrate concentration, initial pH and water matrix on removal of BPS were evaluated and 10 µM BPS could be completely removed in 90 min under the optimal conditions of [BPS]0: [PS]0 = 1: 100, T = 25 ℃, pH0 = 7.0, [N-SWCNTs] = 20 mg·L− 1. Fast removal of BPS was also obtained when reaction temperature reached 65 ℃ without catalyst. There were 15 intermediates identified in total; and hydroxylation, sulfate addition, carboxylation, the cleavage of S − C bond and polymerization were considered as the main transformation pathways of BPS in both two systems based on LC-MS analysis. The proportion discrepancy of •OH and SO4•− involved in two systems led to different distribution and abundance of observed products. The results of transition state calculation further confirmed the reaction potential of hydroxylation, hydrogen atom abstraction and sulfate addition, and the minimum reaction barriers were 22.20, 25.06 and 13.85 kJ/mol, respectively. The present work firstly reveals the overall transformation behavior of BPS in radicals-triggered PS system by combining experimental and theoretical study.

High oxidation potential as well as other advantages over other tertiary wastewater treatments have led in recent years to a focus on the development of advanced oxidation processes based on sulfate radicals (SR-AOPs). These radicals can be generated from peroxymonosulfate (PMS) and persulfate (PS) through various activation methods such as catalytic, radiation or thermal activation. This review manuscript aims to provide a state-of-the-art overview of the different methods for PS and PMS activaton, as well as the different applications of this technology in the field of water and wastewater treatment. Although its most widespread application is the elimination of micropollutants, its use for the disinfection of wastewater is gaining increasing interest. In addition, the possibility of combining this technology with ultrafiltration membranes to improve the water quality and lifespan of the membranes has also been discussed. Finally, a brief economic analysis of this technology has been undertaken and the different attempts made to implement it at full-scale have been summarized. As a result, this review tries to be useful for all those people working in that area.
