[Determination of trace elements in cardiocrinum giganteum by FAAS].
Conditions for simultaneous determination of multi-tract elements in Cardiocrinum giganteum by flame atomic absorption spectrometry were studied. Elements K, Ca, Na, Mg, Fe, Zn, Mn, Cu and Cr in different growth periods of Cardiocrinum giganteum were determined, the relative standard deviation of the method is between 0.20% and 2.1%, and the recovery is between 97.8% and 104.9%. Analytical results were satisfactory. The results showed that some elements essential to human such as Zn, K, Ca, Mg and Mn in Cardiocrinum giganteum are abundant, implying that the nutritive value of Cardiocrinum giganteum is high.
