| Abstract: | In this paper, the method for the determination of As, Pb, Cd, Cr, Cu, Zn, Mn, Fe and Mg in Lentinus edodes by microwave digestion and inductively coupled plasma mass spectrometry had been presented. Microwave digestion comditions and operational conditions of ICP-MS were optimized. The recovery was 92.0%-104.6%, and the RSD was 2.2%~5.3%. The method was simple, fast and accurate. |
