Decomposition of Bisphenol A by electrolyzed acid water (anode water) was examined. The electrolysis has been carried out using a commercially available diaphragm type electrolyzer with Pt electrodes. Simply by mixing bisphenol A aqueous solution with electrolyzed acid water obtained from the electrolysis of a dilute NaCl solution, bisphenol A disappeared and trace amounts of the byproducts such as chloroform have been detected. A similar decomposition of bisphenol A producing chloroform could also be realized in an electrolysis of bisphenol A aqueous solution including NaCl as an electrolyte. The formation and consumption of hypochlorous acid were observed on both operations. When the same operation was conducted with lower concentration of NaCl and hypochlorous acid, some chlorinated bisphenol A were generated and consumption of hypochlorous acid were not observed. It is likely that the decomposition of bisphenol A is a result of oxidation caused by hypochlorous acid produced in the electrolysis of NaCI solution.
