dc.description.abstractThe effect of bromide on the degradation of organic contaminants by advanced oxidation processes (AOPs), especially UV/persulfate (PS)/Fe2+, was investigated in this study. The tested model organic compounds included an active sunscreen ingredient benzophenone-4 (BZ4), the pesticide atrazine (ATZ), the antibiotic ampicillin (AMP), benzene derivatives nitrobenzene (NB) and nitrobenzoic acid (NBA). While most of them have varied but comparable reactivities with hydroxyl radicals, NB and NBA barely react with sulfate radicals. The destruction of these compounds was affected to a different extent by the presence of Br-. ATZ and AMP were the two compounds whose degradation was the most strongly inhibited, followed by BZ4. On the other hand, direct photolysis, photochemical degradation and mineralization of NB were enhanced in the presence of Br- and/or Cl- ions. This study demonstrated the different reactivity of organic compounds towards UV/PS/Fe2+ process in the presence and absence of halides, providing useful information for water decontamination.
