| Abstract: | In This paper, the contents of metal elements in three kinds of desert plants Salix bordensis, Elaeagnus angustifolia and Salix psarnrnophila from Inner Mongolia were determined by ICP-AES technique. The recoveries obtained by standard addition method is between 95.1% and 110.3% ,and its RSD is lower than 3.4%. The results show that major elements such as Na,K,Mg,Ca,AI and plant vital activities essential trace elements Cu, Fe, Mn, Zn have a different contents orders in these desert plants, and 4 elements contents of Cu,Fe,Mn,Zn are lower than the average contents of other terrestrial plants. |
