| Abstract: | An analysis method of As, Cd, Pb, Cu and Hg in yeast by ICP-AES has been studied systematically. The recoveries of the method for As, Cd, Pb, Cu and Hg of standard samples were found to be 94%-106%, while RSD(n=7)is 5.51% for As, 3.83% for Cd, 4.04% for Pb, 2.0% for Gu, and 6.52% for Hg. The method has been applied to the analysis of yeast with satisfactory results, the detecting limit is 0.227μg As/g, 0.0174μg Cd/g, 0.103μg Pb/g, 0.098μg Cu/g and 0.0015μg/Hg/g. |
