本文研究了一个提取居里级~(242)Cm的化学流程,采用TBP萃取色层,除裂片元素,CH_3OH-HNO_3-阴离子交换树脂体系分离Am和Cm,产品中~(241)Am的α放射性与~(242)Cm的α放射性之比达到3×10~(-4)。此流程具有步骤少,操作方便和产品介质简单等优点。
In this paper, we studied a chemical process of extracting curiosity ~ (242) Cm. Amounts of Am and Cm were separated by the extraction of color layers with TBP and CH_3OH-HNO_3-anion exchange resin system. The radioactivity of ~ (241) Am in the product And ~ (242) Cm α radioactivity ratio of 3 × 10 ~ (-4). This process has fewer steps, easy operation and product media, and other advantages.
