| 摘 要： | 介绍的离子交换色谱分离岩石样品Lu-Hf的方法，是对现有方法的改进。整个流程以使用HCl为主，配合少量HF，即可达到有效地分离Hf和Lu的目的，Lu和Hf的回收率在90％以上。经MC—ICP。MS分析，每个国际岩石标样的两个平行样获得了在误差范围内一致^176 Hf／^177 Hf比值，其中BHVO-1、BHVO-2和BCR-2的^176 Hf／^177 Hf比值与国内外文献报道的结果在误差范围内一致。

| Abstract: | The ion-exchange chromatography method presented in this study is modified from pre-existing methods. The scheme involves the elution of matrix and interference elements using HC1 and minor HF, resulting in the efficient separation of Hf and Lu from rock samples, with the recovery of more than 90% Hf and Lu. The ^176 Hf/^177 Hf ratios obtained by MC-ICP-MS for the duplicate solution of individual international rock standard are identified within error, and BHVO-1 ,BHVO-2, and BCR-2 show the ^176Hf/^177Hf ratios in good agreement with the values from the literature. |
