Abstract: A GFAAS method for the determination of Pb in food was proposed in this paper.The food sample was prepared by dissolution or dilution with water.The introduced sample was digested in the interior of graphite tube during ashing step.The method is suitable for those homogeneous water-soluble or emulsion samples and contamination can be avolded.Detection limit and determination limit of this method were found as 0.02 mg·kg-1 and 0.07 mg·kg-1 respectively.The proposed method has been applied to the determination of Pb in more than 20 samples with values of RSD′s (n=5) and recovery in the ranges of 2.0%-7.8% and 85.7%-105.3% respectively.
