使用特效萃取剂P538分离氧化铈,用JY38P型等离子光谱仪进行稀土元素杂质的测定,杂质总量的测定下限为3.6ppm。研究了输出功率、分离效率及非稀土杂质对测定的影响。方法精密度为12％相对误差小于15％
The cerium oxide was separated using the special extractant P538 and the rare earth element impurities were measured with a JY38P plasma spectrometer. The lower limit of determination of the total amount of impurities was 3.6 ppm. The effects of output power, separation efficiency and non-rare earth impurities on the determination were studied. Method precision of 12% relative error less than 15%
