摘要

233

Pa是中子辐照钍制取核燃料

233

U的重要中间体。长期以来人们认为用无机吸附剂来分离、纯化

233

Pa是行之有效的方法

。我们利用在高通量堆中辐照的钍经阴离子交换法分离获得的

233

Pa、

233

[5]

以及天然Th，研究了在HNO

介质中，

233

Pa、

233

U及Th在硅胶、SnO

、Sb

及MnO

四种无机吸附剂上的吸附行为，其中SnO

与Sb

是前人没有作过系统研究的。通过单管平衡实验，我们找到了

233

Pa吸附及解吸的合适条件，并由柱实验证明，

233

Pa可以从U、Th中获得较好的纯化。从柱实验效果看，硅胶与SnO

都有良好的性能，但在实际使用中，SnO

比之硅胶似乎更为理想，因此我们认为SnO

有可能成为分离、纯化

233

Pa的一种有效吸附剂。

Abstract

The absorption behaviours of

233

U and Th on the silica gel

SnO

and MnO

from HNO

medium were studied. From batch experiments it shows that

233

Pa was absorbed by the absorbents while

233

U and Th are not absorbed. From column experiments silica gel and SnO

appeared to be a good absorbents of

233

U and Th. The SnO

with its good physical and chemical properties would be a more effective reagent for isolation and parification of

233

Pa.
