摘　　要：N,N,N′,N′-四丁基-3-氧-戊二酰胺(TBOPDA)对锕系和镧系元素具有较好的萃取性能和较高的辐照稳定性。本文主要研究了辐照对纯TBOPDA和稀释后的TBOPDA萃取性能的影响。研究结果表明,该萃取剂具有较强的辐照稳定性。纯萃取剂在辐照剂量达到1000kGy时,对铀的萃取分配比才有明显下降;;达到100kGy时对铕的萃取分配比有明显下降。稀释剂的加入会使萃取剂辐照稳定性有所下降。N, N, N′, N′-tetrabutyl-3-oxa-pentanediamide (TBOPDA) presents excellent extraction abilities for the actinide and lanthanide elements and exhibits a high irradiation stability. In this paper, the effects of irradiation on extraction of TBOPDA have been studied. It is found that TBOPDA has better radiation stability. When irradiation dose reached 1000 kGy and 100 kGy respectively, the distribution ratios of U and Eu declined remarkably. The addition of diluents resulted in a decline of radiation stability.
