Objective: Explore atomic fluorescence spectrometry and its application in determination of As and Hg in medicinal materials. Method: Determination of As and Hg in Chinese medicinal materials by atomic fluorescence spectrometry using wet digestion. Result: The relative standard deviation of As and Hg which were 0.30% and 0.29%.The recovery of the method 101.3% and 101.0%;The detection limit of As and Hg was 0.029 μg·L-1 and 0.0076 μg·L-1. Conclusion: The method has high sensitivity,precision and accuracy were both meet requirements,it is widely used in determining the contents of As,Hg.
