[Spectrometric determination of trace elements in Tricholoma giganteum Massee].

The eight trace elements in Tricholoma giganteum Massee, including K, Ca, Na, Mg, Fe, Zn, Mn and Cu, were determined simultaneously by flame atomic absorption spectrometry. The relative standard deviation of the method is 0.1%-2.2%, and the recovery is 98.1%-106.4%. The analytical results were satisfactory. The results showed that some elements essential to human such as Zn, K, Ca, Mg and Mn in Tricholoma giganteum Massee are abundant, implying that the nutritive value of Tricholoma giganteum Massee is high.
