| Abstract: | Lead and cadmium are two kinds of harmful element distribute in nature widely. In this paper, lead and cadmium in vegetables were determined by microwave decomposition-graphite furnace atomic absorption spectrometry with microwave digestion. The method is simple, rapid. The recovery are 94.5%-101.5% for lead and 92.0%-97.5% for cadmium. |
