Abstract：In this paper,the contents of trace elements in beans such as Ca， Mg， Mn， Sr， Fe，Co，Ni，Se and Ba were determined by ICP-AES uing nitrifying method of high pressure nitrifying pot, and compared with the results of wet method. The two methods showed no obvious differences. The method proves to be simple， rapid， highly sensitive， accurate and can be used to determine many elements at the same time. In addition， there was little environment pollution.Its recovery is 96.8%-102%, and relative standard deviation is 3.35%.
