结果准确可靠。

Abstract

Objective: To determine the contents of metal elements in Lysimachia christinae H. by FAAS. Method: The samples were digested with the HNO3-HClO4 system and then the flame atomic absorption spectrometry was adopted to determine the contents of five mental elements (Fe

Cu and Zn) in L. christinae from six diferent places. Result: L. christinae contains abundant mental elements. The contents of five mental elements from high to low is Mg

Zn and Cu successively. The additional standard recoveries of samples were between 97.11% and 102.94% with RSD(n=6) of the range from 0.83% to 3.37%. Conclusion: The established method to determine the conetents of Mg

Cu and Zn in L. christinae was of high sensitivity

good stability

precision and accuracy.
