| Abstract: | The method for simultaneous determination of arsenic and antimony in water was established by hydride-generation atomic fluorescence spectrometry in nitric acid medium. Instrument condition, acidity, concentration of potassium borohydride and thiourea-ascorbic acid were selected. The linear relationship of arsenic and antimony was 0-10.0μg/L. The detection limit of arsenic and antimony was 0.02 μg/L and 0.01μg/L, the relative standard deviation of arsenic and antimony determination results was 1.77%-3.72% and 2.95%-4.87%（n=6）, the recovery of standard addition of arsenic and antimony was 98%-106% and 96%-105% respectively. This method has the advantages of simple operation and high sensitivity, it is rapid and easy to spread, which is suitable for simultaneous determination of arsenic and antimony in water. |
