Abstract
A method for the simultaneous determination of 7 trace elements (lead, arsenic, cadmium, chromium, selenium, mercury, and nickel) in meat and meat products by inductively coupled plasma mass spectrometry (ICP-MS) with microwave digestion was established. Samples were pretreated by microwave digestion and determined by ICP-MS with rhodium (Rh) as the internal standard. The microwave digestion conditions and the instrumental parameters were optimized. It was found that the instrumental signal drift and matrix effect could be overcome by using the internal standard method. The developed standard curve was linear in the range of 0 to 20 ng/mL, with a correlation coefficient of more than 0.999. The recoveries of the analytes in spiked samples ranged from 89.4% to 98.9% and the precision expressed as relative standard deviation was less than 5%. The limits of detection for the trace elements were all lower than those stipulated in the Chinese national standards. The proposed method was rapid, accurate, reliable, sensitive and suitable for simultaneous multi-element analysis of meat and meat products.关键词
