| Abstract: | A method has been described for the simultaneous determination of arsenic and antimony in Ganmao Chongji by hydride generation-double channel atomic fluorescence spectrometry (HG-AFS). The experimental conditions that influence the fluorescence intensities of arsenic and antimony were investigated and optimized, and the influence from foreign ions and their eliminations were studied. The detection limits were found to be 0 0903 μg/L and 0 0578 μg/L for arsenic and antimony, respectively. The proposed method was applied to the determination of arsenic and antimony species in Ganmao Chongji. Recoveries were in the ranges of 89 2%～97 8% and 90 8%～101 4% for As and Sb, respectively. |
