I. Siminiceanu, Neamtu M. . Kinetics of Bisphenol-A photodegradation in water by ultraviolet activated hydrogen peroxide. Rev. Chem (Bucharest) (English Edition), 2, pp. 19-22, 2001.

Abstract: Aqueous solution containing 0.52 mmol/L bisphenol-A and various doses of hydrogen peroxide have been irradiated with a UV low-pressure mercury lamp immersed in a batch cylindrical photoreactor. The BPA concentrations and three main products (phenol, DHB, BQ) have been followed by HPLC with a Diode Array Detector. After 20 minutes of irradiation the conversion of BPA was only 16.54% with no H2O2 but as high as 98.13% with 0.49 mmol/L H2O2 added. Using a simple kinetic model, the apparent first-order constant has been derived from the experimental curves.

Keywords: Bisphenol-A, photodegradation, products
