Bisphenol A (BPA) is a precursor used in the synthesis of plastics such as polycarbonates and epoxy resins which are commonly found around our lives and BPA is coating material in making thermal paper. BPA is an endocrine disruptor that negatively affects the ecosystem and the human body. When BPA is released into a natural environment, it does not decompose easily and remains for a long time, and as it absorbed into the body, it can be accumulated. Therefore, it has been a big concern of environmental scientists. Rapid treatment processes are necessary when BPA is released to the water and sediment environment through spill events to minimize the spread of the chemical and adverse effect on the environment. In this study, the decomposition characteristics of BPA were studied by using the Fenton reaction and persulfate oxidation by thermal activation. The variable concentration of hydrogen peroxide and ferrous iron was evaluated for the Fenton reaction. The persulfate was thermally activated at 60 °C. The experiments were carried out in batch-type experiments. Fenton reaction was a rapid treatment method for BPA with the ratio of [Fe2+]:[H2O2]=1:25 and complete decomposition within about 15 minutes. S2O8 showed increased reaction rate at higher oxidant dose but the reaction rate was lower rate than those of Fenton reaction in same concentration of oxidants. The objective of current study is to establish quick and harmless treatment process considering the characteristics of BPA and sediments.
