Abstract
The mongolian medicine erdunwurle was digested by the microwave system.The trace elements of Fe,Mn,Zn,Ca,Mg,K,Sr and Na of which were determined by the ICP-AES under the optimal condition.The recoveries for these elements are 84.8%—124.4%,and the relative standard deviation,RSD was 3.2%.The method is simple,rapid and accurate,and was applied to the determination of mongolian medicine with satisfactory results.
