摘要
用浓硝酸-高氯酸混合酸对蕨麻样品进行消化,采用空气-乙炔火焰原子吸收光谱法测定了样品中矿物元素含量。结果表明,蕨麻中Fe、Mg含量较高,还含有Zn、Cu、Mn、Co等人体必需微量元素,有较高营养价值,测定结果的相对标准偏差在1.738%～17.372%之间。
The sample was digested by HNO3- HClO4. Seven mineral elements including Zn, Cu, Fe, Mn, Co, Mg and Cd in Potentilla anseriana were directly analyzed by air - acetylene flame atomic absorption spectrometry. The result showed that RSD was between 1. 738% and 17. 372%.
