| Abstract: | Pb and Cd in sauce were determined simultaneously by ICP-MS,using microwave digestion for sample handling,In and Re as internal standard.The detection limit of Pb ad Cd were 0.002mg/L and 0.001mg/L respectively,the degree of precision was more than 3% and the recovery was 97%～103%.Therefore,this method is simple,rapid and accurate with low detection limit. |
