Abstract
Hawthorn leaves were treated by nitric acid and perchlorate,and trace elements in hawthorn leaves were determined by FAAS.The results showed that there were rich Ca,Mg,Fe,Mn in hawthorn leaves.The recovery ratio of the method is from 99.6% to 105.0% in the standard addition analysis and the RSD is less than 0.71%.The result is accurate.
