酰胺类萃取剂萃取分离铕的研究进展

Progress in Extraction and Separation of Europium with Diamide Extractants

酰胺类萃取剂容易合成,热稳定性好,能完全燃烧,对环境友好等一系列优点,已广泛的用来从核燃料的后循环中萃取分离镧系元素和锕系元素。论述了使用不同类型的酰胺类萃取剂萃取及其分离铕的研究,重点讨论了丙二酰胺类和丁二酰胺萃取剂、酰胺莢醚类萃取剂、吡啶二甲酰胺类萃取剂、乙酰胺基胺类萃取剂萃取分离铕的最新研究成果,同时对这几类催化剂萃取铕的萃取效果进行了比较和讨论。

Amides have been widely used in the extraction and separation of lanthanides and actinides from the cycle of nuclear fuel due to their advantages of easy synthesis,good thermal stability,complete combustion and environmental friendliness.In this paper,the research progress of the extraction and separation of europium by amide extractants have been reviewed.The latest research results of the extraction and separation of europium by malondiamide and succinamide extractants,amidopodands extractants,pyridinedicarbonamide extractants,acetamide amine extractants were mainly discussed.At the same time,the extraction effects of these catalysts were compared and discussed.
