Objective To establish FAAS method for determinging 6 metalements in gaomaoling granules. Methods Microware digestion was used to dispose the samples; FAAS method was applied to determine Ca,Mg,Fe,Zn,Cu and Mn in the gaomaoling granules. Results The results showed that there were relatively rich trace elements in gaomaoling granules. The average recovery rate was 95. 11%~ 106. 23%. Conclusion The result measured by this method is considered to be accurate.
