Methods Samples were digested with microwave digestion system. and the contents of Cu , Pb , Cd and Cr were determined by graphite fumace atomÎc absorp- tion spectrometry (GFAAS); the contents of As and Hg were determined by atomic fluorescence spec忧。metry (AFS) , and the reproducibility and recovery of the method were also examined. Results As and Hg contents in most of the products were below the limit. Only Cu , Pb and Cd contents exceed the limit. The recovery was 86. 3 %陶 113.4% and RSD was 10.4 %. Con- c1usions The method is simple and accurate , and can be used for the det桔rmination of heavy metal in Chinese herbs.
