Abstract

Plutonium from acidic waste solutions has been recovered quantitatively using tri-n-octylamine (TnOA) in xylene and americium using a mixture of octylphenyl-N-N- diisobutylcarbamoylmethylphosphine oxide (CMPO) and TBP in dodecane by extraction and extraction chromatographic methods. The Pu ( IV ) TnOA species extracted into the organic phase from higher nitric acid concentrations has been confirmed as (R(3)NH)(2)Pu(NO(3))(6) (where R(3)N = TnOA by employing slope analysis as well as spectrophotometric studies.

摘要

已通过萃取和萃取色谱法，使用二甲苯中的三正辛胺（TnOA）从酸性废液中定量回收钚，并使用十二烷中的辛基苯基-N-N-二异丁基氨甲酰甲基氧化膦（CMPO）和磷酸三丁酯（TBP）的混合物从酸性废液中定量回收镅。通过斜率分析以及分光光度研究，已证实从较高硝酸浓度的有机相中萃取的Pu(IV) TnOA物种为(R(3)NH)(2)Pu(NO(3))(6)（其中R(3)N = TnOA）。
