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。
The sensitizing effect of cationic surfactant cetyltrimethylammonium bromide on the fluorescence reaction of terbium-ilmenite was studied. The optimal reaction conditions and the composition ratio of complex were determined. Made a comparison. The trace amount of terbium in the rare earth synthetic samples was determined. The result is satisfactory.
