摘要
介绍了ＴＲＰＯ－冠醚－亚铁氰化钾钛处理模拟生产堆高放废液流程中α核素的分离分析方法。根据料液成分的差异，推荐了３种萃取分离方法。实验结果表明，推荐方法消除了强β、γ核素及高盐分对α测量的影响，回收率均在９８％以上。
The solvent extraction methods of separating α-nuclides from high level liquid waste(HLLW) treated by TRPO process are recommended. Different separation processes are applied according to the variou s compositions of HLLW. The influence of high salt concentration and high levelβ、γradioactivity are eliminated. The measurement accuracy of α-nuclides is improved and the determination limit is lowered.
