| Abstract: | A method for determination of Pb and Cd in Du Qing Yao by GFAAS with microwave digestion was presented.The sample was digested with HNO3-H2O2 and the contents were determined by calibration curve method.The contents of Pb and Cd were 9.087μg/g and 1.480μg/g,respectively.The recoveries for Pb and Cd were in the range of 95%—107% with RSD of 4.5%—5.2%（n=8）,and the results were satisfactory. |
