| Abstract: | A rapid and effective method for determination of Pb and Cd in chinese medicine by GFAAS was established.The influence factors on microwave digestion were studied.The operating conditions of GFAAS were optimized.The detection limit for Pb and Cd is 0.145ng/mL and 0.0119ng/mL in linear range of 0-20ng/mL and 0-2ng/mL,respectively.The recovery are in the range of 96.7%- 103.6%. |
