Abstract:Objective:A method for the determination of arsenic and mercury in fermental cordyceps sinensisfy powder by atomic fluorescence spectrometry has been developed.Methods:The criterion and sample were dissolved by microwave and analyzed by AFS-9130 double-channel atomic fluorescence spectrometer.Meanwhile,we optimized the experiment condition.Results:At the best condition,the relative standard deviation of arsenic and mercury were 0.75 and 1.8.The coveries of arsenic and mercury ranged from 94.5% to 104.0% and 89.4% to 107.8%,respectively.Conclusion:The results indicate that the above method is highly sensitive,repeatable and applicable.
Keywords:Atomic fluorescence spectrometry    Simultaneous determination    Arsenic    Mercury    Fermental cordyceps sinensisfy powder
