HEDPA介质中TRPO对超铀元素的萃取

EXTRACTION OF TRANSURANIUM ELEMENTS FROM HEDPA MEDIUM BY TRPO

研究了在HEDPA介质中TRPO对超铀元素的萃取性能。结果表明 :在一定浓度HEDPA存在的条件下 ,除Tc(Ⅶ )外 ,TRPO对Am(Ⅲ ) ,Pu(Ⅲ ) ,Pu(Ⅳ ) ,Np(Ⅳ ) ,Np(Ⅵ )都具有很低的萃取分配比。

Extraction of transuranium elements from HEDPA medium by TRPO is studied.The results show that distribution ratioes of Am(Ⅲ),Pu(Ⅲ),Pu(Ⅳ),Np(Ⅳ),Np(Ⅵ) are all very low by TRPO from HEDPA medium except Tc(Ⅶ). The stripping agent HEDPA can be used to strip actinides from TRPO solution.
