摘要: 本文研究了Al、Fe、Sc-CAS混合表面活性剂多元络合物的形成条件。这些体系有着较高的灵敏度和良好的选择性,并且可允许多种掩蔽剂存在,故可用于纯稀土氧化物中Al、Fe、Sc的同时测定。方法简单快速,不需任何分离手续。

Abstract: The conditions of the formation of multicomponent complexes of Al, Fe, Sc, with CAS in the presence of mixed surfactant have been studied. These color reactions were found to have high sensitivity and selectivity. The method is very simple, no separation is necessary and it may be used for the simultaneous determination of Al, Fe, Sc in pure rare earth oxides.
