摘　　要：酰胺类萃取剂作为锕系元素的一种优良新型萃取剂 ,具有易合成、耐辐射、不易水解、辐射产物易洗涤、不影响萃取过程和能完全燃尽等优点 ,被认为是能取代TBP应用于核工业的最有前途的萃取剂之一。近十几年来 ,人们对此类萃取剂研究较多。本文将对N ,N -双取代酰胺类、N ,N ,N′ ,N′-四取代双酰胺类。Amide extractant is one of the best extractants for actimium elements.And it has the advantages of easy synthesis,enduring radiation,difficult hydrolysis,washing the radint matters easily,no effect on the extracting process and being burnt off.So it is one of extractants with better future applied to nuclear industry instead of TBP.Several amide extractants in recent years are discussed in this paper,including N,N-disubstituted amides,N,N,N′,N′-tetrasubstitutedglutaramides and cycloamides.
