摘要
用火焰原子吸收光谱法(FAAS)测定了红枣中K、Ca、Mg、Cu、Mn、Zn、Fe等7种微量元素的含量。实验方法加入标准样回收率在99.4%—105.2%之间,RSD在0.4%—1.3%之间,分析结果令人满意。红枣中含有丰富的微量元素,其含量由高到低的排列顺序为:Fe、K、Ca、Mg、Zn、Mn、Cu,说明红枣具有很高的营养价值。
The seven trace elements in juj determined simultaneously by FAAS with the ube, including Zn, Cu relative standard de , Mn, Fe, Mg, K and Ca, were viation of 0. 4%-1. 3% and recovery of 99. 4%-105. 2%. The analytical results are satisfactory. The Jujube elements with the order of Fe〉K〉Ca〉Mg〉Zn〉Mn〉Cu,and has high nutriti value.
