近年来,对岩石和矿物的分类、成因、形成条件及演化过程等,用稀土元素作出图解较多,有逐渐取代常量及微量元素图解之趋势。因此,迫切需要研究出一种检出限低、准确、简便、经济和快速测定痕量稀土的分析方法。我们在前人的基础上,用水平式ICP发射光谱和去溶装置,在试样分离、富 In recent years, the classification of rocks and minerals, causes, formation conditions and evolution process, with rare earth elements to make more diagrams, there is a gradual replacement of the constant and trace elements of the trend. Therefore, there is an urgent need to develop a low detection limit, accurate, simple, economical and rapid determination of trace rare earth analysis. On the basis of our predecessors, we use horizontal ICP emission spectrometry and desolvation equipment, in the sample separation, rich
