摘要: 应用高灵敏显色体系同时测定稀土混合物是分析化学的难题之一。前文用因子分析方法同时测定了三组分稀土混合物,本文在前人工作基础上,应用自浮因子分析法,对稀土混合物的同时测定进行了研究。结果表明,采用双显色体系,通过可控条件的选择,增加各稀土元素间光度性质的差异,较满意地进行了四组分稀土混合物的同时测定。

关键词: 自浮因子分析, 稀土, 同时测定

Abstract: The principle of free floating factor analysis (FFFA) is described. In the dual colour developing system of RE-TBA and RE-MTB-CPB, we successfully determined the four component rare earth mixtures of La, Sm, Dy and Lu simultaneously using this method. The optimum conditions for the simultaneous determination of the four elements are also discussed.

Key words: Free floating factor analysis, Rare earth, Simultaneous determination
