摘要
研究了稀土配合物的荧光衰减动力学特性及其影响因素,拟定出长寿命组份存在下测定短寿命组份及短寿命组份存在下测定长寿命组份的2种时间分辨荧光光谱分析方法。用于纯稀土氧化物及合成水样中痕量铕和镝的测定,获得了满意的结果。
The fluorescent decay kinetic properties of rare earth complexes and the effects with surfactants, additive ligands and synergistic ions were studied. The fluorescence lifetime were same for the different fluorescence emission of each complex. According to the fluorescent decay properties, two time-resolved fluorimetries were proposed for determination of rare earth ion having longer fliorescence lifetime and shorter fluorescence lifetime. Results are satisfactory for the determination of trace amounts europium and dysprosium in oxides of rare earth and synthetic water samples.
