| Abstract: | The methods for direct determination of Selenium and Molybdenum in traditional Chinese medicine by pyrolytic coated graphite furnace atomic absorption spectrometry (GFAAS) with nickel and palladium as the mixed matrix modifler and using two ashings were described.The relative standard deviation is Iess 4.2% for the determination of Selenium and less 5.0% for molybdenum.The recovery of standard addition is from 93.7% to105.8% for Selenium and from 94.6% to 101.9% for Molybdenum.The methods have been applied to the determination of Selenium and Molybdenum in 100 traditional Chinese medicin e with satisfactory results. |
