【摘要】 本文报告了从加速器辐照后的银靶中分离和纯化¹⁰⁹Cd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¹⁰⁹Cd。将此工艺用于热分离实验,所得¹⁰⁹Cd样品中未检出其他放射性杂质,化学收率为99%。更多还原

【Abstract】 A simple and effective method for the separation and purification of ¹⁰⁹Cd produced by cyclotron is reported. The Ag target was dissolved with HNO₃. Ag was separated by electrochemical exchange; then ¹⁰⁹Cd was purified by anion exchange. The procedure was used to produce carrier-free ¹⁰⁹Cd successfully. No γ impurities were found in the ¹⁰⁹Cd obtained. The chemical yield was 99%.更多还原
