随着实验技术的进步以及多接收电感耦合等离子体质谱仪（MC-ICP-MS）和热电离质谱仪（TIMS）的发展，近年来Ba 同位素的分析方法取得了显著进展。分析精度（δ^138/134Ba，2SD）从之前的1 ‰ 提高到好于0.05 ‰。文章综述了近年来高精度Ba 同位素分析方法（溶液法）的发展历程，总结了国内外实验室关于不同类型样品的消解、Ba 元素化学纯化流程以及Ba 同位素质谱测定等方法，并对国内外多个实验室已发表的各类标准物质的Ba 同位素组成进行统计。研究结果可为Ba 同位素激光原位分析提供参考，为后续分馏机理解析和应用研究提供技术支撑。

With the advancement of analytical techniques and the development of mass spectrometers (MC-ICP-MS and TIMS), the barium isotopic analysis methods have been significantly improved. The analytical precision of δ^138/134Ba is better than 0.05 ‰ (2SD) compared with 1 ‰ (2SD) in previous studies. This article reviewed the barium isotope analysis methods (solution methods) in the past ten years, and summarized the digestion methods, the chemical purification procedures, and the instrumental analysis of barium isotopes for different types of samples. In addition, the barium isotopic compositions of various reference materials analyzed in different laboratories are summarized in this study. We hope that this paper will help researchers to establish in situ analysis methods of Ba isotopes, and also provide support in Ba isotope fractionation mechanism deduction and geological applications.
