| 摘 要： | 本文提出了用ＩＣＰ－ＡＥＳ法直接同时测定高纯氧化钇中１４个稀土和１６个非稀土杂质元素的分析方法，对被测元素的 谱线、氧化钇基本及背景影响进行了研究，用标准加入法测出氧化钇基准中的微量杂质元素，消除了由于忽略基准中的杂质元素含量给高纯氧化钇分析测定带来的误差，同时对工作条件进行了优化。方法中各被测元素的检出限为0.003～1.31ug/g，能够满足生产过程中的质量控制及进出口商品检验

| Abstract: | High purity yttrium oxide is widely used in various fields. The purity of products affects their quality directly. It is necessary to develop a sensitive method for the accurate determination of trace impurities in high purity yttrium oxide.
In this paper, the authors put forward an analytical method that 30 elements, i.e. La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yh, Lu, Al, Ba, Ca, Cu, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Si, Sr, Ti, V, Zn in high purity Y2O3 are determined directly by ICP-AES. The writers studied the spectral interference of yttrium and the effect of Y203 matrix and background, and selected the spectral lines of determined elements. The trace impure elements in Y2O3 standard are determined with standard addition method, and the determined results are used as 1ow standard values, so that the determining errors can be cleared up because of neglecting trace impurity elements in Y2O3 standard, and the optimum operating condition is chosen. The detection limits of 30 elements are from 0.003 to 1.3μg/g. This method can satisfy the needs of quality control of high purity Y 203 products and commodity inspection. |
