Abstract

A novel integrated direct and indirect electrochemical copper dissolution was developed. Indirect oxidation process on the cathode is attributed to the H2O2 and ?OH via oxygen reduction reaction and Fenton-like reaction, respectively. The results indicated that large amount of reactive species can be electro-generated to accelerate the dissolution of copper under the optimum conditions of preset potential 0.25 V or current density 6 mA/cm2, respectively.
