| Abstract: | The measurement of several impurity elements, such as As,Cd,Cr,Pb,Sn and Sb in Chinese traditional medicines by means of ICP AES, and different digestion methods for sample pretreatment were investigated. The effect of medium, amount of acid and coexistent elements in these Chinese traditional medicines were also studied.Meanwhite the accuracy of the measurement results was verified by a so called method named "recovery of standard". A sample pretreatment process named as "dry ashing" was proved to be effective for ICP AES analysis. Experimental results showed that this method is simple and quick with high accuracy. |
