| Abstract: | By nitrifying method of high pressure nitrifying pot, the contents of four trace elements Mn,Cu,Fe and Mg in black rice were determined by ICP-AES and AAS. The contents of trace elements by ICP-AES and AAS were at approach,and the former was better. The rccoverys are in the range of 92.2%-109% ,and RSD is less than 2.67%. The experiment proved that the black rice,as a kind of healthy food,contained rich useful trace elements for human body. |
