| Abstract: | Objective ] The research aimed to establish the simultaneous determination method of metal elements in animal viscera by micro- wave digestion inductively coupled plasma mass spectrometry （ICP-MS）. Method ] Combining microwave digestion and ORS-ICP-MS tech- nology, the determination method of many kinds of metal elements in animal viscera was established. Result ] Under the optimal conditions, 12 kinds of metal elements showed good linear correlation in the range of 0 - 10 mg/L and the linear correlation coefficients were more than0. 999. The limited range of this method was 0. 038 - 0. 219 μg/L. When the adding level in the animal viscera samples was 0.01 - 3 500 μg/g, the addition recoveries was 92.9% - 104.1%. Conclusion] This method was simple, rapid, with high accuracy and sensitivity. This method was suitable for the simultaneous determination of multiple kinds of metal elements in animal viscera. |
