| 摘 要： | 本文研究了一种新型萃取剂用于Am(Ⅲ)/Eu(Ⅲ)的分离,并做了以下条件的研究:(1)不同酸度的影响(0.1-0.3mol/LHNO3);(2)不同稀释剂的影响,采用I 241Am和152-154Eu作示踪剂。结果表明在3mol/LH-NO3体系中241Am能被萃取出来,而152-154Eu几乎不能被萃取。在0.1-0.3mol/LHNO3条件下,用硝基苯胺稀释剂,萃取分离系数达到70。

| Abstract: | Separation of Am(Ⅲ)/Eu(Ⅲ) is investigated by under some condition:(1) acidity of 0.1-3.0mol/LHNO3,(2)different dilute agents,using 241Am and 152-154Eu as the trance elements,respectively.The results show that Am3+ can be extracted from the solution of 3mol/LHNO3 and Eu3+ can nearly not be extracted.The separation coefficient can get to 70 under the condition of more than 3mol/LHNO3 and using nitromethane as dilute agent. |
