摘要
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。
Waste ABS plastics were stripped with the solution mixed of hydrochloric acid and hydrogen peroxide,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 electrolytic duration,were further studied through single factor and orthogonal test methods to determine the optimum parameters 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.
