| Abstract: | Objective The contents of Fe, Zn, Mg and Ca in rumex nepalensis were analyzed by flame atomic absorption spectrometry. Methods The sample was pretreated with HNO3 - HClO4 and measured quantitatively through calibration curve method. Results It was shown that the sample has rich in human essential metal elements. The recoveries are between 96. 90 % and 102. 3 %, and the relative standard deviation is less than 5%. Conclusion The result measured by this method is considered to be accurate. |
