摘要: 本文提出用显色剂——对-乙酰基偶氮胂作淋洗剂,阳离子交换分离钍与稀土(铀、钪),流出液可直接用光度法测定,将分离和测定结合起来的新方法.操作较简便快速.分离测定了矿石中稀土及钍,结果尚属满意.

Abstract: In this paper, a azo-type color forming reagent——p-Acetylarsenazohas been developed for an eluting agent. It has been used for the cation exchange separation of thorium and rare earths (uranium, scandium). The eluting components can be determinated directly with spectro-photometric technique. The method is more simple and rapid. The separation and continuous determination of the rare earths and thorium in the samples of ores were carried out. The results are satisfactory.
