| Abstract: | In the present work, the impurity-elements As, Cd, Cr, Pb, Sn and Sb in Chinese traditional medicines were simultaneously determined by ICP-AES, and different digestion methods for sample treatment were investigated. The effects of medium, amount of acid and coexistent elements in Chinese traditional medicines were also studied. Meanwhile, a dry-ashing method was applied for sample pretreatment. The accuracy of the measure-ment results was verified by means of recovery of standard. It was proved that ICP-AES is a simple and rapid method for determing the above six elements in Chinese traditional medicines and has high accuracy. |
