本文采用CL-P507萃淋树脂色谱法进行高纯氧化镨中稀土杂质元素的分离浓缩,浓缩倍数为1000倍,浓缩物用碳粉吸附法进行光谱测定。测定下限为∑RE9ppm,变异系数为5—26％。化学分离周期约16小时。可用于纯度为5个9的氧化镨中14个稀土杂质元素的测定。
In this paper, CL-P507 Leaning Resin Chromatography separation and concentration of rare earth impurities in high-purity praseodymium oxide, concentration 1000 times, the concentrate was measured by carbon adsorption spectrophotometry. The lower limit of determination is ΣRE9ppm and the coefficient of variation is 5-26%. Chemical separation cycle of about 16 hours. It can be used for the determination of 14 rare earth impurity elements in praseodymium oxide with a purity of 5 9.
