研究了酰胺荚醚N ,N ,N′,N′ 四丁基 3 氧 戊二酰胺 (TBOPDA)和N 50 3(N ,N′ 二乙基庚酰胺 )以及TBOPDA与N 50 3的组合萃取剂在硝酸介质中对U (Ⅵ )、Pu(Ⅳ )、Am(Ⅲ )、Eu(Ⅲ )和其他一些金属离子的萃取行为 ,稀释剂为 4 0 %正辛醇 煤油。用 0 0 75mol/LTBOPDA +0 5mol/LN 50 3/ 4 0 %辛醇 煤油为萃取剂 ,从模拟高放废液中分离U(Ⅵ )、Pu(Ⅳ )、Am(Ⅲ )和Eu(Ⅲ )的微型混合澄清槽实验结果表明 :在A槽 ,大于 99 99%的U(Ⅵ )、Pu(Ⅳ )、Eu(Ⅲ )和Am(Ⅲ )被萃入有机相 ;在R1槽 ,U(Ⅵ )被定量反萃 ,83 %的Pu(Ⅳ )和 36%的Am(Ⅲ )被反萃入水相 ;在R2槽中残留的Pu(Ⅳ )、Am(Ⅲ )和Eu(Ⅲ )可被定量反萃下来。该流程可有效提取高放废液中的锕系元素 ,并可对其进行组分离。
The effects of amide pallidines N, N, N ’, N’tetrabutyl 3oxoglutaramate (TBOPDA) and N 50 3 (N, N’-diethylheptanamide) and a combination of TBOPDA and N 50 3 extractants The extraction behavior of U (Ⅵ), Pu (Ⅳ), Am (Ⅲ), Eu (Ⅲ) and some other metal ions in nitric acid medium was 40% diluent n-octanol kerosene. U (Ⅵ), Pu (Ⅳ), Am (Ⅲ) and Eu (Ⅲ) were isolated from simulated high level liquid waste by using 0 0 75mol / LTBOPDA + 0 5mol / The experimental results of micro-mixing clarification tank show that U (Ⅵ), Pu (Ⅳ), Eu (Ⅲ) and Am (Ⅲ) are more than 99.99% (Ⅳ), Am (Ⅲ), and Eu (Ⅲ) were re-extracted into the aqueous phase with 83% of Pu (Ⅳ) and 36% of Am (Ⅲ) Quantitative back-extraction down. This process can effectively extract the actinides in high-level liquid waste and can separate them from each other.
