Oxidation of bisphenol A by permanganate: reaction kinetics and removal of estrogenic activity.
Water Sci Technol. 2013; 67(8):1867-72.WS

Abstract

The kinetics for reaction between bisphenol A (BPA) and permanganate was examined over pH range of 5.0-9.9 and the estrogenic activity of aqueous BPA solution after oxidation was assessed by yeast two-hybrid assay. Reaction kinetics follows the second-order rate law, with the apparent second-order rate constant of 15.1 ± 1.1 M(-1)s(-1) at pH 6.0 and 25°C and the activation energy of 48.7 kJ/mol. The kinetics exhibits pH dependency and the specific rate constants related to speciation of BPA are 50 ± 28 M(-1)s(-1), 9.6 (±0.6) × 10(3) M(-1)s(-1) and 1.4 (±0.1) × 10(4) M(-1)s(-1) for BPA, BPA(-) and BPA(2-), respectively. The results of the estrogenic/antiestrogenic activity test show that there is a hysteresis for the removal of estrogenic activity of aqueous BPA solution at pH 7.3. Removal of BPA is completed in 10 min, but complete removal of estrogenic activity requires a further 20 min.
