摘　　要： 目的运用火焰原子吸收光谱法对木槿中茎和叶的Fe、Zn、Mg、Ca、Cu 5种金属元素含量进行了测定。方法用浓V(HNO3)+V(HClO4)=4+1消解样品,采用标准曲线法测定。结果所测的样品中含有丰富的人体必需微量元素。回收率在95.10%～105.00%之间,RSD小于2%。结论该法简单、准确,结果令人满意。 Objective The contents of Fe, Zn, Mg, Ca and Cu in hibiscus syriacus were analyzed by flame atomic absorption spectrometry. Method The samples were pretreated with V（ HNO3 ） ＋ V（ HC104 ） =4 ＋ 1 and measured quantitatively through calibration curve method. Result It was shown that the samples has rich in human essential metal elements. The recoveries are between 95.10% and 105.00%, and the relative standard deviation is less than 2%. Conclusion The result measured by this method is considered to be accurate.
