摘　　要： 运用火焰原子吸收光谱法直接测定了绿豆和红豆中Fe、Cu、Mg、Ca、Mn和Zn六种金属元素的含量。用浓硝酸微波消解样品,采用标准曲线法测定。所测定的样品中含有丰富的人体必需金属元素且大部分元素的含量接近,采用此方法回收率在99.04%～109.09%之间。本方法简单、准确,结果令人满意。 The contents of Fe,Cu,Mg,Ca,Mn and Zn in Vigna radiata and V.angularis were analyzed by flame atomic absorption spectroscopy.The sample was digested with HNO3 in microwave oven,and detected by calibration curve method.The results showed that abundant necessary elements in V.radiata and V.angularis were observed,and the recoveries were between 99.04% and 109.09%.In conclusion,it is a simple,accurate and satisfiable method for detecting metallic elements.
