本文拟定ICP-AES直接测定低钇混合稀土组分的方法,确定了适宜的测定条件。方法准确、快速、简便。样品分析结果与X-荧光光谱法及导数分光光度法相符。各元素测定相对标准偏差为1.4～3.3％。
In this paper, ICP-AES direct determination of low-yttrium mixed rare earth components of the method to determine the appropriate measurement conditions. The method is accurate, fast and easy The results of the sample analysis are in accordance with the X-ray fluorescence spectrometry and the derivative spectrophotometry. The relative standard deviation of each element was 1.4 ~ 3.3%.
