Determination of total arsenic in food by hydride generation atomic fluorescence spectrometry

To study the method of hydride generation atomic fluorescence spectrometry in determining the content of Total arsenic in food.Adopt AFS-230a hydrochloric acid as medium to contrast with standard substances.Detection limit was 1.27μg/L, liner range was 0～100μg/L, recovery rate was 83%～96%.[Conclusion]This method is simple, fast with high sensitivity, precision and accuracy. It has wide liner range and low detection limit with no toxicity. It can be widely applied.
