| Abstract: | Objective:To develop a atomic fluorescence spectrometric method for the determination of heavy metals(As,Cd) in Gongliuxiao.Method:Sample were digested with microwave system,and the As,Gd were directly analyzed by atomic fluorescence spectrometric.Result:For the analyzed heavy metals,the correlative coefficient of the calibration curves was over 0.9992,the recovery was 91.5%-97.8%,RSD was less 5%.Conclusion:The method is convenient and highly sensitive.The method had been applied to the determination of trace heavy metals in traditional Chinese medicine with satisfactory results. |
