| Abstract: |
| In order to detect four kinds of trace heavy metals, Pb, Cr, Cd and As content, by inductively coupled plasma mass spectrometer （ICP-MS） in soft capsule of soybean phospholipids conveniently, quickly and accurately, a kind of pretreatment method of refrigeration smashing－microwave digestion was established. The results showed that soft capsule shells treated by refrigeration smashing presented small and uniform particle size. In addition, microwave digestion had advantages of short time, simple operation and less reagent consumption. Four metals (Pb, Cr, Cd and As) were quantitative analyzed by ICP-MS, and their recovery rate was between 82.6％ and 92.9％. The test could provide reference for the quantification of heavy metals in soft capsule. |
