从辐照后的镉靶中分离~111In

SEPARATION OF ~111 In FROM IRRADIATED CADMIUM TARGET

摘要: 用自制的HDEHP萃淋树脂研究并建立了从辐照过的Cd靶中分离111In的方法。111In的放化回收率为 98% ,37MBq111In中 ,金属离子的总量为 0 0 4 35μg。

Abstract: High purity 111 In is obtained by reversed phase partition chromatography from an irradiated cadmium target with HDEHP extractive eluting resin. The yield of 111 In is over 98 %. Overall content of Cd,Ni,Cu and traces of extraneous metal ions is less than 0.5 μg in 37 MBq 111 In.
