摘　　要：本文采用相对灵敏度因子，研究了９９．９９９％－９９．９９９９％的Ｈｏ２Ｏ３和Ｌｕ２Ｏ３中４０余种杂质元素的火花源定量分析方法，讨论了谱线干扰。做了加入回收及生理性实验，大多数元素的相对标准偏差在３０％以内，检测下限为０．００ｘμｇ／ｇ。A method for the quantitative determination of 40 trace elements in high-purity Ho2O3 and Lu2O3 samples is described by relative sensitivity factor spark source mass spec-trometry. The recovery of impurity elements, precision of method and interference of spectral line are discussed. The relative standard deviation is less than 30%. The detection limit of the method is 0.00x μg/g.
