摘要: <正> 离子交换-有机淋萃法是在离子交换树脂从水相吸附金属离子基础上,用有机萃取剂作为淋洗液,萃取解吸被吸附元素以达到化学分离目的的一种方法。早期应用的淋洗液都是与水混溶的有机溶剂,如乙醇等,得到了良好的分离效果。70年代初,J.Korkisch等应用了与水不相混溶的有机萃取剂TBP作为淋萃液,在阴离子交换树脂上进行了一些分离分析工作。有关的其它工作很少见到报道。Abstract: The ion exchange-organic extraction elution is a method of chemical separation, which . is based on the exchange adsorption of metal ions from aqueous phase by the resin, which is then eluted with organic extractants. This method has the advant
