摘　　要：提出了石墨炉原子吸收光谱法测定蜂胶中铅含量的方法,样品采用微波消解,用磷酸二氢铵基体作为改进剂,方法的精密度(n=7)在1.1%～1.3%之间,回收率在91.8%～101.9%之间。A method of GF-AAS for determination of lead in propolis was proposed. The sample was treated with microwave assisted sample digestion, and NH4 H2 PO4 was used as matrix modifier. Values of RSD （n= 7） of the method were found in the range of 1.1%-1.3% and values of recovery in the range of 91.8%-101. 9%.
