摘要
研究了以邻苯二酚紫（ＰＶ）为萃取剂，用阳离子表面活性剂在混合有机溶剂（正己烷∶环己醇＝９∶１）中形成反相微胶团萃取金属离子与邻苯二酚紫（ＰＶ）螯合物的条件，探讨了ＨＣｌ介质中溶液酸度、萃取剂和表面活性剂的浓度等条件对金属离子的反相微胶团分配行为的影响．该体系可用于Ｚｒ４＋－Ａｌ３＋、Ｚｒ４＋－Ｇｅ４＋的定量萃取分离．
The condition of formation of metals by reverse micro micelles and chelate of catechol violet (PV) is studied with catechol violet (PV) as extractive solvents and using cation surfactants in mixture of organic solvents ( n hexane∶ n hexyl alcohol=9∶1).The effect of acid,extractive solvents and surfactants ect in HCl midium on the distribution of behaviour of metals by reverse micro micelles is discussed.The system is used in the separation of quantified extraction for Zr 4+ Al 3+ ,Zr 4+ Ge 4+ .The extractive organization of extraction by reverse micro micelles is discussed.
