采用盐酸和双氧水构建的溶液对废ABS塑料电镀件进行退镀，退镀液中含铜、镍等金属，采用电解法回收退镀液中的铜。通过单因素及正交试验法，考察了电流密度、电解液循环流量、电极距、电解时间等工艺条件对电流效率及铜回收率的影响，确定了铜回收过程的最佳工艺参数：电流密度416.0 A/m2、电极距1.4 cm、溶液循环流量3.0 L/h、电解时间40 min。

×aste ABS plastics were stripped with the solution mixed of hydrochloric acid and hydrogen perox-ide,and electrolytic process was employed to recycle copper aften stripping. Effects of process conditions on current efficiency and copper recovery rate,such as ampere density,electrolyte circulation flow,electrode spacing and elec-trolytic duration,were further studied through single factor and orthogonal test methods to determine the optimum pa-rameters of copper recovery processing. Finally,the optimal process conditions were carried out:Current density, 416. 0 A/m2;Electrode spacing,1. 4 cm;Solution circulation flow,3. 0 L/h;Electrolytic duration,40 min.
