在1:20万区域化探扫面工作中,微量砷、锑的分析方法既要有很高的灵敏度,满足化探工作的要求,又要简便、快速,适应大量样品的分析。本文在前人工作的基础上,对氢化物发生无色散原子荧光法测定微量砷、锑进行了方法研究,建立了一个特别适应于大批化探样品中砷、锑的分析方法。方法具有灵敏度高、重现性好、干扰少、成本低、效率高、简便快速等优点,可测定含砷、锑0.1ppm 以上的样品。
In the area of 1: 200,000 regional exploration surface, trace arsenic and antimony analysis methods should have high sensitivity, meet the requirements of geochemical exploration work, and be simple, rapid and suitable for the analysis of a large number of samples. Based on the previous work, a method for the determination of trace arsenic and antimony by hydride generation atomic fluorescence spectrometry has been studied. A new analytical method for arsenic and antimony in a large number of geochemical exploration samples has been established. The method has the advantages of high sensitivity, good reproducibility, less interference, low cost, high efficiency, simple and quick, etc. The method can be used to determine the samples containing 0.1ppm or more of arsenic and antimony.
