| Abstract: | Methods for the determination of eight metal elements by AAS in Ejiao, one of the Chinese traditional medicines,are developed in this paper.With HNO3-HClO4 mixed acid digesting Ejiao sample in a 50ml testing tube, Cu is assayed by flame AAS, Cr, Cd and Ph determined by GFAAS,and the As,Sb and Sn determined by hydride generation AAS.Hg can be assayed by cold atom AAS with the sample pretreated by a mixture of HNO3,H2SO4 and hydrogen peroxide in a 50ml testing tube and heated on the water bath. |
