分离化学是大多数分析程序的核心，以确定人造和自然发生的材料的稀土含量。这些程序广泛应用于矿物勘探、基础地质学和地球化学、材料科学和核工业。依赖于对镧系元素阳离子半径和阳离子交换相转移反应（使用各种不同的固体介质）敏感的络合剂的水溶液的色谱方法在这些程序中取得了最大的成功。在本报告中，我们将简要总结完成此类分析的最重要方法。我们将详细讨论基本的水（和两相）溶液化学，它解释了分离效果良好的原因，并解释了为什么其他分离不太成功。
Separations chemistry is at the heart of most analytical procedures to determine the rare earth content of both man-made and naturally occurring materials. Such procedures are widely used in mineral exploration, fundamental geology and geochemistry, material science, and in the nuclear industry. Chromatographic methods that rely on aqueous solutions containing complexing agents sensitive to the lanthanide cationic radius and cation-exchange phase transfer reactions (using a variety of different solid media) have enjoyed the greatest success for these procedures. In this report, we will briefly summarize the most important methods for completing such analyses. We will discuss in some detail the basic aqueous (and two-phase) solution chemistry that accounts for separations that work well and offer explanations for why others are less successful.
