γ辐照后30%TRPO-煤油体系对镅的萃取与保留

Extraction and Retention of ~(241)Am With γ-irradiated 30%TRPO-kerosene

摘要: 研究了30%TRPO 煤油辐照后对镅的萃取与保留性能的变化。结果表明:当吸收剂量大于2MGy后,萃取剂对Am的萃取性能稍有降低,反萃时,Am无保留。对Am萃取性能变化的原因进行了探讨。

Abstract: The extraction and retention of 241Am with γirradiated 30%TRPOkerosene are studied in the paper. The results show that the distribution ratio of 241Am with irradiated 30%TRPOkerosene decreases a little when the absorbed dose exceeds 2 MGy. 241Am loaded on the extractant could be stripped completely with 5.5 mol/L HNO3.
