三维荧光光谱法同时测定钐、铕、铽和镝

Three-Dimentional Fluorimetric Simultaneous Determination of Dysprosium,Europium,Samarium and Terbium

本文研究了TFA-TOPO-Triton X-100体系中钐、铕、铽和镝的荧光光谱,拟定了三维荧光光谱同时测定的分析方法。该法用于混合稀土和氧化钇中钐、铕、铽和镝的同时测定,获得了满意的结果。

The fluorescence spectra of dysprosium, europium, samarium and terbium in the system of TFA-TOPO-Triton X-100 were studied. The three-dimentional fluorimetry for the simultaneous determination of these four rare earths was developed. The technique has been applied to the determination of Dy, Eu, Sm and Tb in their mixtures and yttrium oxide, and the satisfactory results were gained.
