希土元素的光谱定量分析,都以化学光谱法为主。不经化学处理直接粉末分析方法,最常见的是电弧浓缩法,而撒样法不能被应用,原因是被分析元素不仅受矿样中第三元素的影响,而且还受被分析元素在矿样中存在形式差异的影响。另外,撒样法的分析灵敏度也比垂直法低。因此,对于较难挥发的希土元素,用撒样法定量分析,怎样消除矿样中被分析元素存在形式的影响,以及提高分析灵敏度,是要解决的关键问题。
Quantitative analysis of the Greek soil elements are based on chemical spectrometry. Direct powder analysis without chemical treatment, the most common arc concentration method, and sprinkling method can not be applied because the elements being analyzed not only by the impact of the third element in the sample, but also by the analysis of elements in the mineral sample In the form of differences in the impact. In addition, Sampling method analysis sensitivity than the vertical method. Therefore, for the more volatile rare earth elements, using sprinkling method quantitative analysis, how to eliminate the impact of the existence of the analytic elements in the ore sample, as well as to improve the sensitivity of the analysis is the key issue to be solved.
