摘要
采用二-（2-乙基己基）磷酸（简称D2EHPA）作为萃取剂,以磺化煤油为稀释剂,研究了硫酸盐溶液体系中萃取分离Zn（Ⅱ）,Cd（Ⅱ）的性能,考察了萃取时间、pH、萃取剂浓度、水相锌镉离子浓度、温度等因素对锌、镉萃取分离过程的影响。实验结果表明,D2EHPA/煤油体系对锌萃取分离效果良好。
The solvent extraction of zinc and cadmium from sulfate solutions using di-2-ethyl hexyl phosphoric acid（D2EHPA）,in sulfonated kerosene as diluent has been studied.The influence of pH value of aqueous phase,zinc and cadmium concentration,extractant composition,temperature and other factors on extraction equilibrium were investigated.The results show that D2EHPA diluted by sulfonated kerosene has a good extraction performance for zinc from sulfate solution.
