原子吸收法是一种较好的定量分析法,具有灵敏度、准确度高,选择性较好等优点。其缺点之一是,测定砷、硒、锑、铋、等挥发性元素的灵敏度低。氢化物发生技术与原子吸收相结合已成功解决了这一问题——提高了原子吸收法测定那些挥发性元素的灵敏度,并得到了广泛应用。氢化法的发展史已有文章介绍。文献对氢化物发生—原子吸收光谱分析(HG—AAS)作了全面综述。近年来,我国分析工作者对HG—AAS这一痕量分析技术进行 AAS is a good quantitative analysis method, with the advantages of high sensitivity, high accuracy and good selectivity. One of its shortcomings is the determination of arsenic, selenium, antimony, bismuth, and other volatile elements of low sensitivity. The combination of hydride generation and atomic absorption has successfully solved this problem - increasing the sensitivity of atomic absorption spectrometry for the determination of those volatile elements and has been widely used. The history of hydrogenation has been introduced. The literature provides a comprehensive review of hydride generation-atomic absorption spectroscopy (HG-AAS). In recent years, our analysts have conducted a trace analysis of HG-AAS
