| Abstract: | Yeast powder contains trace molybdenum indispensible for human health.The method of microwave digestion and ICP-MS is adopted to determine the contents of trace molybdenum in yeast powder.The determined detection limit is 0.010 μg/g,the labeled recovery rate is 94.2%～101.6%,and the variation factor(RSD,n=6)is 2.21%.The determined results are likely to meet the analytical requirements which shows that this method is prompt and accurate. |
