ABSTRACT: The metal-doping into the photocatalyst was evaluated for the photocatalytic degradation of bisphenol
A in aqueous solution with ZnO powder. Au/ZnO, Ag/ZnO and Cu/ZnO were tested in the
present work. Ag-doping ZnO was effective for the improvement of efficiency for the photocatalytic
degradation of bisphenol A in water. The optimum doping concentration of silver was found to
be 3 wt%. The pseudo first-order rate constant with 3 wt% Ag/ZnO was 1.3 times better compared
with bare ZnO. The photocatalytic degradation of treatment for the wastewater containing bisphenol
A is simple, easy handling and low cost.
