| Abstract: | A method of GF-AAS for determination of lead in propolis was proposed.The sample was treated with microwave assisted sample digestion,and NH4H2PO4 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%. |
