[Influencing factors and kinetics of oxidation of bisphenol A in water with sodium hypochlorite].
Huan Jing Ke Xue. 2007 Nov; 28(11):2544-9.HJ

Abstract

The degradation and its kinetics of sodium hypochlorite oxidation of an endocrine disruptor-bisphenol A (BPA) were studied. The influencing factors were investigated, such as chlorine dosage, initial concentration of BPA, pH value, bromide ion concentration and temperature etc. The results showed that the degradation of BPA by sodium hypochlorite followed pseudo-first-order kinetics. The pH value influenced the degradation of BPA greatly. The pseudo-first-order rate constant of the reaction between BPA and HOCl reached the maximum value of 0.544 3 min(-1) during pH 8 - 9. Moreover, the bromine ion in water would accelerate the degradation of BPA, and the whole reaction did not follow the rule of pseudo-first-order kinetics. The temperature influenced the reaction greatly, and it followed Van' t Hoff Rule. The removal efficiency of BPA would increase with increasing temperature.
