摘要
本文报告了从加速器辐照后的银靶中分离和纯化^(109)Cd的简便、高效方法。靶物用硝酸溶解后,首先利用银离子与铜的电化学交换反应除去溶液中的银离子,然后利用717型阻离子交换树脂纯化^(109)Cd。将此工艺用于热分离实验,所得^(109)Cd样品中未检出其他放射性杂质,化学收率为99%。
A simple and effective method for the separation and purification of ^(109)Cd produced by cyclotron is reported. The Ag target was dissolved with HNO_3. Ag was separated by electrochemical exchange; then ^(109)Cd was purified by anion exchange. The procedure was used to produce carrier-free ^(109)Cd successfully. No γ impurities were found in the ^(109)Cd obtained. The chemical yield was 99%.
