目前,火焰原子吸收光谱法已逐步用来测定普通试剂中的杂质元素,由于灵敏度的限制,还很难直接用它来测定高纯试剂中的微量杂质元素。因此,如何将分离富集技术与火焰原子吸收光谱法结合起来使其也能在高纯分析中发挥作用就成了高纯分析工作者的一个研究课题。有的文章已介绍了有机溶剂萃取在火焰原子吸收光谱上的应用。近年来发表最多的是有关此方法在环境检测中应 At present, flame atomic absorption spectrometry has been gradually used to determine the impurity elements in common reagents. Due to the limitation of sensitivity, it is difficult to directly measure the trace impurity elements in high purity reagents. Therefore, how to combine the separation and enrichment technology with flame atomic absorption spectrometry to make it work in high-purity analysis becomes a research subject of high-purity analysis workers. Some articles have introduced the application of organic solvent extraction in flame atomic absorption spectrometry. Published in recent years is the most relevant method in the environmental testing should be
