Formation of halogenated disinfection byproducts during the degradation of chlorophenols by peroxymonosulfate oxidation in the presence of bromide

Advanced oxidation processes based on sulfate radical (SO4−) have obtained great attention in water treatment and in-situ ground water/soil remediation. In this study, the degradation of chlorophenols (CPs) in Co2+ activated peroxymonosulfate (PMS) oxidation process was explored. It was found that 2-chlorophenol, 2,4-dichlorophenol, and 2,4,6-trichlorophenol could be effectively removed in Co2+/PMS oxidation process. Presence of Br− greatly...
