| Abstract: |
| In this paper, we introduced the determination of 9 kinds of metal elements, arsenic, cadmium, lead, nickel, chromium, copper, mercury, antimony and zinc in pork muscle, by microwave digestion and ICP-MS. The linear range of standard curve was from 0 to 50ng/mL, the detection limit was 1.2ng/mL ~ 22.5ng/mL, and the precision of the method was 0.28% ~ 4.39%. All the recovery rates in meat were between 81.5% and 112.6%. The method we used in this paper is simple, rapid and accurate, which may greatly improve the detection time and efficiency. |
