Abstract
- The degradation efficiency of bisphenol A (BPA) in aqueous solution was investigated in UV 254 nm combined with potassium ferrate [ UV/Fe(VI) ] process・ The main active components for BPA oxidation were identified, and the possible degradation pathways of BPA were also proposed・ The results showed that the synergistic degradation of BPA in UV/Fe(VI) process followed the pseudo second-order kinetics, and its degradation rate was enhanced by 98. 94% and 67. 17% compared with single UV and Fe(VI), respectively・ The removal rate of BPA reached 91 ・ 46% when the BPA concentration was 220 |jimol/L, Fe(VI) concentration was 50 |jimol/L, the system temperature was 25 °C and pH 6. creasing temperature and pH, the presence of humic acid and CO| can enhance the degradation efficiency. The dominated reactive oxidation species in UV/Fe(VI) system were Fe(V), Fe(IV), superoxide radicals and hydroxyl radicaL The degradation of BPA mainly underwent the demethylation, hydroxylation and ring opening reactions in UV/Fe(VI) system.
