摘要: 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。Abstract: This work describes a new method for preparing242Cm in curie quantity. The chemical separation of242Cm is accomplished by TBP extraction chromatogra-phy and CHSOH-HNO3 anion exchange. This process has the advantages of less chemical steps and simpler operation. The product is good in quality. The a activity ratio of241 Am/242Cm of the product is 3 ×10-4, and the media of product is just CH3OH-HNO3 with no salt in it.
