| 摘 要： | 提出了一种阳极直接电化学溶解与阴极间接溶出耦合溶出铜的新方法，阴极间接氧化是基于氧气还原反应和类芬顿反应产生H2O2和?OH. 结果表明，在最佳电压0.25 V或电流密度6 mA/cm2下，电化学体系能产生大量活性物种，铜溶出率在直接阳极溶出的基础上大幅提升. |

| 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. |
| Keywords: | copper dissolution electrochemical integration hydroxyl radical acid solution |
