本文采用交流电弧高浓度溶液干渣法测定纯氧化钆中14个稀土杂质元素。试样在氩/氧气氛中激发,直接光谱测定。方法相对标准偏差不大于5%。方法简单,经加入回收试验和大量实际试样的分析获得满意结果。
In this paper, 14 rare earth elements in pure gadolinium oxide were determined by dry-slag method of AC arc high concentration solution. The sample is excited in an argon / oxygen atmosphere and the direct spectrum is measured. Method relative standard deviation of not more than 5%. The method is simple and satisfactory results have been obtained by adding the recovery test and a large number of actual samples.
