摘要: 研究了阳离子表面活性剂溴化十六烷基三甲铵对铽-钛铁试剂荧光反应的增敏作用,确定了最佳反应条件及络合物的组成比,并与测定铽的七个荧光体系做了比较。测定了稀土合成样中的微量铽。结果令人满意。

Abstract: The scnsitization of CTMABon Tb-Tiron fluorescence reaction was investigated. The optimum reaction conditions and the composition of the complex were established. The comparisons with seven fluorescence reaction of Tb show that the sensitivity of the Tb-Tiron-CTMABreaction is the highest. The content of Tb in the synthetic samples of rare earths was determined with satisfactory results.
