| Abstract: | Objective:To establish a method to determine the residence of Lead in Chinese herb. Methods:Dissolve the sample by microwave,and determine the content of Lead by graphite furnace atomic absorption spectrometry. Results:Recovery rate was 98. 8 % with RSD 1. 85 % accordingly. Conclusion:The method established was simple,feasible,accurate,highly sensitive and reliable,which can be used to control the residence of Lead in Chinese herb. |
