| Abstract: | Objective:To establish a method for the determination of tin and in food by Hydride Generation-Atomic Fluorescence Spectrometry.Methods:The working condition of the determination were studied and tin in food were determinated by Atomic Fluorescence Spectrometry.Results:The detection limits of this method were found to be 0.046 μg/Lfor tin,and the RSD were 3.27% for tin.The recovery rates of standard spiking for tin were in the range of 96.33%～99.54%.Conclusion:The method is sensitive,accurate and rapid.It can be adopted for determination of tin in food. |
