摘要

稀土元素是地质研究的重要工具。REE含量低和/或干扰钡含量高的地质样品可能会影响REE浓度的准确测定。开发能够将REE与其他基质成分分离的化学分离方法是克服这一问题的彻底方法。在本研究中，开发了一种简单的基于RE树脂的分离方法，并对各种样品溶液（混合元素溶液、页岩、碳酸盐和花岗岩）进行了测试。该方法具有良好的稀土元素回收率，能有效地去除基体元素，尤其是钡。该方法适用于高钡岩石样品中铕含量的精确测定。

Separation of Rare Earth Elements In Geological Samples with High Concentrations of Barium Using RE Resin

Rare earth elements (REE) are important tools in geological studies. Accurate determination of REE concentrations can be affected in geological samples with low REE levels and/or high levels of interfering barium. Development of chemical separation methods allowing to isolate REE from other matrix components is a thorough approach to overcome this issue. In this study, a simple, RE resin-based separation method was developed and tested for a variety of sample solutions (mixed element solutions, shale, carbonate and granite). The method shows a good REE recovery and is efficient for the removal of matrix element, and notably Ba. The method is suitable for precise determination of the Eu contents in rock samples with high barium content.
