摘要
研究了从高放废液泥浆离心母液中用HDEHP TiOA、TiOA、TRPO分离2 37Np、2 39Pu、2 4 1Am等α核素的分离方法。提出了分离程序及总α的测定方法。分离流程对2 39Pu、2 37Np、2 4 1Am的回收率分别为 99%、88%、99%。
The slovent extraction method of separating α nuclides from high level liquid waste (HLLW) is established by HDEHP, TiOA and TRPO. A separation procedure and analytical method for 237 Np, 239 Pu, 241 Am and all radioactivity of α nuclides in HLLW is recommended. The analysis results from HLLW show that the whole recovery is 88 %, 98 % and 99 % for 237 Np , 239 Pu and 241 Am, respetively.
