Simultaneous Determination of Arsenic and Antimony in Steel by Double Channel Atomic Fluorescence Spectrometry with Hydride Generation Technique

    摘要
  • 摘要: 建立了一种氢化物发生双道原子荧光光谱法同时测定钢中痕量砷和锑的方法.对实验条件进行了优化，在最佳工作条件下，砷和锑的检出限分别为0.012 ng/g和 0.034 ng/g，RSD分别为1.24％和1.97％.将本法应用于钢中的砷和锑的测定，采用加标回收实验控制方法的准确性，砷的回收率为96%~98%，锑的回收率98%~102%.

     

    Abstract: A analytical method was proposed for simultaneous determination of arsenic and antimony in steel by hydride generation double channel atomic fluorescence spectrometry. Under optimized conditions, the determination limits of arsenic and antimony were 0.012 ng/g and 0.034 ng/g, respectively. RSD were 1.24％ and 1.97％. The experiment of spiked recovery was carried out in order to validate the method. The recovery was from 96% to 98% for arsenic, 98% to 102% for antimony.
