Abstract—Bisphenol A is not only an important chemical raw water in order to provide basic datas for BPA migration in the
material, but also an environmental estrogen. This article environment or wasted plastic recycling.
examines the reactions of bisphenol A in sub-critical water. The Efforts have been made in recent years to develop cost-effective
experimental factors, such as ratio of solvent to BPA (), technologies for BPA position and detoxification [2]. Xu [4]
