| Abstract: | Objective： To establish the method for determination of two kinds of heavy metals （ As, Hg） in Glycyrrhiza of Sang Chart Zhi Ke Fang by atomic fluorescence spectrometry （AFS）. Methods： Microwave digestion and determination by AFS. Results： The content of As is 0. 3857mg/Kg; The content of Hg is 5. 8274 μg/Kg. Accord with the chinese pharmacopoeia under the provisions of Glycyrrhiza. The correlative coeffi- cient of the calibration curves was over 0. 9997, the recovery was 99.5% - 102. 8%, RSD≤〈2.2%. Conclusion： The method is quick , convenient , acquired accurate and highly sensitive. |
