摘要

本文研究了从吸附载带

233

Pa的二氧化锰沉淀和中子辐照二氧化钍中制取纯

233

U的方法。实验结果表明，应用阴离子交换与甲基膦酸二（1－甲庚）酯萃取相结合的方法可以制得高纯度

233

U。该

233

U经液体闪烁及同位素源激发X荧光分析证明无其他放射性杂质存在，可作为铀的优良示踪剂。本文也研究了制备

233

标准源的方法。

Abstract

This paper describes a procedure for purification of

233

U obtained from old MnO

precipitate containing

233

Pa and irradiated ThO

. Anion exchange and DMHMP solvent extraction were used for this purpose. The purity of

233

U was checked by liquid scientillation counting and radioisotope X ray fluorescence analysis. A method for the preparation of standard

source is also given.
