本文研究了2-噻吩甲酰三氟丙酮(TTA)-邻菲绕啉(Phen)-吐温20胶束体系荧光法测定钐、铕时钙离子的熄灭效应和草酸钙共沉淀法的最佳条件。方法已用于水系沉积岩和塘积物等地质试样中痕量钐、铕的测定并得到满意的结果。
In this paper, the best quenching effect of calcium ions and the calcium oxalate coprecipitation method for the determination of samarium and europium by fluorescence spectrometry of 2-butanoyltrifluoroacetone (TTA) -phenanthrene-Tween 20 micellar system condition. The method has been applied to the determination of trace amounts of samarium and europium in geological samples such as sediments and sediments in water and satisfactory results have been obtained.
