摘　　要：以P204为萃取剂对锌钴混合溶液中的锌与钴进行萃取分离,探索了相关因素对萃取分离效果的影响。结果表明,在萃取水相pH=4、萃取相比1.0、P204浓度10%、萃取时间10min、振荡速率100r/min的条件下,锌的单级萃取率达到35%左右,而钴的萃取率仅为2%左右,通过四级萃取,锌萃取率达到98%。Zinc and cobalt were extracted from solution with P204 as extractant.The effects of relevant factors on extraction were investigated.The results show that extraction ratio of single stage of zinc and cobalt is about 35% and 2%respectively under the optimum conditions including pH of aqueous phase of4,O/A=1.0,P204 concentration of 10%,extraction time of 10 min,and oscillation rate of 100r/min.Zinc extraction ratio of four stage is 98%.
