| Abstract: | Objective：To establish a method for determination of Arsenic （As） in infant foods. Method：The infant foods were dissolved by microwave and Arsenic in them was determined by double-channel hydride generation-atomic fluorescence spectrometry. Results：The arsenic content was linear with the fluorescence intensity in the range of 0μg / L - 160.0μg / Lwith correlation coefficient of 0.998 8. The detection limit of this method was 0.038 2μg / L. Recovery experiment was carried out and was simple,rapid,accurate and high sensitive. Arsenic generation-atomic fluorescence spectrometry. recovery was 93.47%-98.51%. Conclusions： The method in the infant foods could be determined by hydride.generation-atomic fluorescence spectrometry. |
