摘要
本文按无机体系,脂肪族二元羧酸、芳香族二元羧酸、杂环类二元羧酸、亚氨基类二元羧酸及其它体系分类,分别评述了荧光分析法测定钐、铕、钆、铽、镝等稀土元素的研究状况。展望了有机二元羧酸作为荧光试剂联合测定稀土元素的可能性。
The article reviews the advance of fluorescence spectrophotometric determination of samarium, europium, gadolinium, terbium and dysprosium in organic dicarboxylic acid system and compared with inorganic salts, fatty dicarboxylic acid, aromatic dicarboxylic acid, heterocyclic acid, amino dicarboxylic acid and other systems for fluorescence analysis of rare earth elements。The paper also looks ahead of the possibility for simultaneous spectrofluorimetric determination of rare earth elements, i.e.Sm^(3+), Eu^(3+), Gd^(3+), Tb^(3+), Dy^(3+) in organic dicarboxylic acid systems.
