“…Under ideal conditions, this chemical treatment can convert organic pollutants into less toxic molecules, such as carbon dioxide, water, and inorganic salts. The commonly used oxidants are permanganate (MnO 4 − ), Fenton reagent (Fe 2+ /H 2 O 2 ), and ozone (O 3 ) [12][13][14][15]. The mechanism of Fenton reagent (Fe 2+ /H 2 O 2 ) in reactions has been known to produce •OH radicals, which can cleave C-H bonds of organic compounds, turning them into environmentally benign final products [16,17].…”

“…•À (0.450 mole) were similar. The production of equimolar concentrations of the reactive species was responsible for the enhanced removal of COD and pathogen in the O 3 /PMS process (Deniere et al 2022). A indistinguishable observation of pathogen removal was observed for the O 3 /PS process (100% TVC of bacteria in 60 min with PS dosage of 1 mM L À1 ).…”

“…Furthermore, in real water matrices, • OH were identified as the main radical contributors which is the opposite from the results obtained in deionized water. This shift was attributed amongst others to the presence of chloride, which is a radical scavenger of SO4 •-and results in extra production of • OH (Deniere et al, 2022;Yang et al, 2015).…”

“…Trace organic compounds (TrOCs) such as pharmaceuticals, pesticides and personal care products are often found in water bodies at low concentrations (ng/Lµg/L), and are associated with long-term toxicity, endocrine disrupting effects and antibiotic resistance (Luo et al, 2014;Rogowska et al, 2020). The ozone-activated peroxymonosulfate process (O3/PMS) is an advanced oxidation process, and has been gaining increasing interest for the removal of TrOCs in water (Cong et al, 2015;Deniere et al, 2022Deniere et al, , 2018Shao et al, 2019;Wu et al, 2019;Yang et al, 2015). The O3/PMS process relies on the production of two types of radicals, i.e.…”
