塩素化ビスフェノールA類の分析法開発および下水処理工程における生成
Chlorinated bisphenol A congeners are unintentionally generated from bisphenol A and its brominated products such as tetraboromobisphenol A in sewage treating process with sodium hypochlorite. Chloro- and bromo- bisphenol A are of large interest as probable precursors of halogenated dioxins. However, no method was found for separately determining the chloro- and the bromo- bisphenol A congeners. A measurement method has been developed to separately determine bisphenol A and all of the chlorinated and the brominated congeners possibly generated from bisphenol A by LC/MS/MS.
