中文摘要: 以N902为萃取剂,从废弃印刷线路板氨性浸出液中萃取回收铜,研究萃取剂浓度、相比(O/A)、萃原液初始pH和时间对铜萃取率的影响。结果表明,室温下N902萃取铜最优条件为:萃取剂浓度15%、O/A=1︰2、料液初始pH=10、萃取时间2.5 min。在此条件下Cu2+萃取率达98.62%,用2 mol/L硫酸溶液对负载有机相进行一级反萃4 min,Cu2+反萃率达89.91%,其溶液可满足电积提铜的要求。
Abstract:Copper was extracted with N902 from ammoniacal leaching solution of waste printed circuit boards. The effects of extraction agent concentration, extraction phase ratio (O/A), initial pH value of extraction solution and extraction time on copper extraction rate were investigated. The results show that copper extraction rate is 98.62% under the optimum conditions including extractant concentration of 15%, O/A=1︰2, initial pH of 10, and extraction time of 2.5 min. Stripping rate of copper is 89.91% with 2 mol/L sulfuric acid solution for 4 min. The solution can meet the requirement of copper electrowinning.
