| 摘 要： | 将噻吩甲酰三氟丙酮－氧化三正辛基磷萃取体系应用于纸上荧光法同时测定钐和铕，该液用量少、操作简便快速。经处理的滤纸可使钐和铕的检出限分别达到1．0和0．05ng。将方法应用于混合稀土氧化物中xng级的钐、0.0x ng级铕的同时测定，结果满意。

| Abstract: | The TTA TOPO hexane extraction system is used in the simultaneous determination of Sm and Eu by paper fluorimetry. The detection limits of Sm 3+ and Eu 3+ are found to be 1.0ng and 0.05ng respectively. The proposed method is proved to be simple and rapid, and has been successfully applied to the analysis of rare earth oxide samples for determination of Sm and Eu at nanogram concentration levels. |
