Abstract：Ten kinds of dominant plants in Vanadium/Titanium mine area were collected, the contents of heavy metals including Pb, Zn, Cu, Cr, Cd and Ti of which aboveground and underground parts were determined by ICP-AES using microwave digestion, respectively. All samples of the plants were digested with HNO3-H2O2 system. The relative standard deviation was less than 5% for all the elements，and the recoveries were 92.90%～103.85% by adding standard recovery experiment. This method was simple，sensitive and precise and can perform simultaneous multi-elements determination compared with conventional method of the plants determination，which could satisfy the sample examination request and provide scientific rationale for determining inorganic elements of plants.
