电感耦合等离子体发射光谱法（ICP-OES）因其灵敏度高、重现性好等优点，已成为测定稀土元素（REE）、钪和稀土元素(y)的一种很有前途的技术。然而，天然样品组成的变化可能会在分离伴随元素（基体元素）时造成严重的问题。本文提出了8种主元素和27种微量元素的简化稀土分离方法。在离子交换过程中，一些主要的基质元素根据其种类和数量的不同，对轻稀土（LREE）的回收率有一定的抑制作用。介绍了两种相似树脂的分离特性。一些痕量基质元素分离不充分。定量了分离后基质元素残留量对稀土元素测定的影响和干扰。最后，对一些稀土元素间干扰进行了描述。通过对标准物质的分析，验证了所建立方法的正确性。
Due to its sensitivity and reproducibility, inductively coupled plasma optical emission spectrometry (ICP-OES) has developed into a very promising technique in the determination of the rare-earth elements (REE), Sc, and Y. However, the changing composition of natural samples may cause severe problems during separation from concomitant elements (matrix elements). In this study a simplified version of REE separation from 8 major and 27 trace elements is proposed. Some major matrix elements, depending on their kind and quantity, cause a specific depression of recovery rates of light REE (LREE) during the ion exchange process. The separation characteristics of two similar resins are described. Some trace matrix elements are separated inadequately. This effect and the interference of matrix element residues after separation on the REE determination are quantified. Finally, some RE interelement interferences are described. The developed methods are verified by the analyses of reference materials.
