摘　　要：研究了酰胺荚醚 (PAⅡ )和二 (1 甲基庚基 )乙酰胺 (N 50 3)在硝酸溶液中对U(Ⅵ ) ,Eu(Ⅲ ) ,Sr(Ⅱ )和Fe(Ⅲ )的萃取。结果表明 ,PAⅡ对U(Ⅵ ) ,Eu(Ⅲ ) ,Sr(Ⅱ )均有良好的萃取性能 ,N 50 3只萃取U(Ⅵ ) ,两种萃取剂对Fe(Ⅲ )The extraction of U(Ⅵ), Eu(Ⅲ),Sr(Ⅱ) and Fe(Ⅲ) with PAⅡ(amide podand) and N503(bis(1 methylheptyl) acetoamide) as extractants from nitric acid solutions has been studied.The results show that U(Ⅵ) ,Eu(Ⅲ) and Sr(Ⅱ) can be extracted with PAⅡ, but N503 can only extract U(Ⅵ). Either PAⅡ or N503 can not extract Fe(Ⅲ) from nitric acid solution.
