Abstract

The twelve trace elements in the Tricholoma matsutake,including K,Ca,Na,Mg,Fe,Pb,Cd,Co,Cr,Zn,Mn and Cu were determined simultaneously by flame atomic absorption spectrometry.The relative standard deviation of the method was 0.08%~2.32%,and the recovery was 97.1%~108.3%.The analytical results were satisfactory.Results showed that there were high level of K,Na,Ca,Mg and a little harmful elements Cd,Pb in the three kinds of Tricholoma matsutake samples,and other six trace elements which had benefit of human were also rich.
