Oxidation of bisphenol F (BPF) by manganese dioxide
摘要：
Bisphenol F (BPF), an environmental estrogen, is used as a monomer in plastic industry and its environmental fate and decontamination are emerging concern. This study focused on the kinetics, influencing factors and pathways of its oxidation by MnO2. At pH 5.5, about 90% of BPF was oxidized in 20min in a solution containing 100μM MnO2 and 4.4μM BPF. The reaction was pH-dependent, following an order of pH 4.5>pH 5.5>pH 8.6>pH 7.5>pH 6.5>pH 9.6. Humic acids inhibited the reaction at low (≤pH 5.5) and high pH (≥pH 8.6) at high concentrations. In addition, metal ions and anions also suppressed the reaction, following the order Mn2+>Ca2+>Mg2+>Na+ and HPO42>Cl>NO3≈SO42, respectively. A total of 5 products were identified, from which a tentative pathway was proposed.
