摘要

在热铀处理的Purex流程中，放射性钌（

103+106

Ru）在硝酸溶液中的化学状态极其复杂，了解其萃取行为对提高裂变产物的去污系数十分重要

［1］

。在提钚的萃取过程中引入了亚硝酸钠，但是在NaNO

存在下研究放射性钌在TBP-HNO

体系中的萃取行为尚未报道。本文首先测定了在NaNO

-HNO

溶液中30%（

）TBP－煤油对HNO

和HNO

的萃取平衡，然后测定了硝酸浓度、NaNO

浓度以及RuNO原始料液经不同方法处理后对钌分配比的影响，并且探讨了在NaNO

存在下提高Purex萃取流程中放射性钌去污系数的一些可能途径。此外还采用Kenny-Martin技术来研究RuNO各类络合物的萃取行为。
