| Abstract: | This paper use ICAPQ plasma mass spectrometry and atomic absorption graphite furnace method was developed for the determination of lead in food than in the experiment. The comparison results are the recovery rate of 95%.The conclusion is that Atomic absorption graphite furnace method results are accurate, ICAPQ plasma mass spectrometer measuring results are accurate, Determination of speed, The cost is too high. More suitable for a certain technology, capital of small and medium-sized laboratory. |
