Electrochemical degradation of aqueous bisphenol A using Ti/SnO2-Sb/Ce-PbO2 anode

Abstract

The electrochemical degradation kinetics and energy consumption of aqueous bisphenol A (BPA) were investigated using Ti/SnO2-Sb/Ce-PbO2 anode. The electrochemical degradation of BPA followed the pseudo-first-order kinetics. Different influence factors, i.e. current density, BPA initial concentration and Na2SO4 concentration, on the degradation kinetics and energy consumption were evaluated. The optimal degradation kinetic rate and energy consumption were 0.067 min-1 and 9.96 Wh/L, respectively. Electrochemical oxidation process was effective in the degradation of aqueous BPA.
