研究了用两种不同来源的 2 羟乙基 1 ,1 二膦酸 (HEDPA)配制的不同硝酸浓度、不同HEDPA浓度的溶液对 30 %TRPO(混合三烷基氧膦 ) /煤油和 2 0 %TRPO 2 0 %TBP(磷酸三丁酯 ) /煤油中UO2 2 + 、Pu(Ⅳ )、Am3+ 和TcO4- 的反萃。提出了用HEDPA为反萃剂的TRPO流程。
The effects of different concentrations of HEDPA solution with 30% TRPO (mixed trialkylphosphine oxide) / kerosene and 20% H 2 PO 4 were studied by using two kinds of HEDPA prepared from two different sources. TRPO 2 Back extraction of TBP (tributyl phosphate) / UO2 2 +, Pu (Ⅳ), Am3 + and TcO4- in kerosene. A TRPO scheme using HEDPA as stripping agent was proposed.
