Solvent extraction process is applied for the extraction of actinides/lanthanides from waste water produced in nuclear industry. Various extractants have been developed for this purpose. More recently separation scientists have shown extensive interest toward ionic liquids (ILs) due to their unique properties. ILs have extensively been used as extraction medium for the recovery of rare earths and actinides or modified to task specific ionic liquids (TSILs); where ionic liquid part has been covalently attached to the extractants. This article highlights some conventional extractants, the use of these extractants in IL medium and the development of TSILs. The effect of medium on extraction efficiency has also been discussed.

室温离子液体中的分子萃取剂和用于分配锕系/镧系元素的特定离子液体的概述

溶剂萃取工艺用于从核工业产生的废水中萃取锕系/镧系元素。为此目的开发了多种萃取剂。最近，分离科学家对离子液体 (IL) 表现出广泛的兴趣，因为它们具有独特的性质。ILs 已被广泛用作回收稀土和锕系元素的提取介质，或被修改以用于任务特定的离子液体 (TSIL)；其中离子液体部分已与萃取剂共价连接。本文重点介绍了一些常规萃取剂、这些萃取剂在 IL 培养基中的使用以及 TSIL 的开发。还讨论了介质对提取效率的影响。
