Sulfate radicals-based advanced oxidation technology in various environmental remediation: A state-of-the–art review

Kinetics and reaction mechanism of photochemical degradation of diclofenac by UV-activated peroxymonosulfate

“…20,21 Moreover, the selectivity and half-life of sulfate radical (30-40 ms) are higher and longer than those of hydroxyl radical (1 ms). [22][23][24] Thus, sulfate radical-based AOPs (SR-AOPs) have a good application prospect in removing organic pollution. 25 Currently, peroxymonosulfate (PMS) and peroxydisulfate (PDS) are the common oxidants utilized to generate SO 4 c À .…”

Preparation of Mn2O3/MIL-100(Fe) composite and its mechanism for enhancing the photocatalytic removal of rhodamine B in water

“…13,14 Sulfate radical can be generated by activation of persulfate via traditional methods such as using UV, heat, ultrasonication, transition metals, and photocatalysts. 15,16 Among them, the activation of persulfate by photocatalysis is usually considered as a green and promising route due to its low energy consumption, high recyclability, and lower photoexcited electron-hole recombination.…”

Ca-Al-Containing Slag As an Advanced Fenton System for the Remediation of Acid Sulfate Soil

“…Calcite and magnesite were used to remediate acidified forest soil (Iljkic et al, 2019), and after 7 years of application, the pH of soil moisture was increased, and the Al concentration was decreased (Iljkic et al, 2019). Advanced oxidation processes have been widely used in soil remediation, such as ozone (Testolin et al, 2021), photocatalysis (Mambwe et al, 2021), electrochemical oxidation (Brillas, 2021), and chemical methods (using hydrogen peroxide, permanganate, and persulfate) (Neyens and Baeyens, 2003;Ushani et al, 2020). Highly active free hydroxyl radicals are produced during Fenton oxidation, which can oxidize S 2in ASS.…”
