摘　　要：苹果经微波消解,用火焰原子吸收光谱仪测定其矿物质元素铁、锌、铜、钙、镁、钠、钾等含量。加入标准溶液测定方法的回收率,消解条件对测定结果有影响。比较测定结果,提出了重视苹果皮的营养价值。该方法适用于苹果及苹果脯中铁、锌、钙、镁、钠、钾等多种元素的测定。After microwave digestion,the content of Fe,Zn,Cu,Mg,Na,K in apple samples is determined by air-acetylene flame FAAS. Adding standard solution in the samples, the recovery ratio is determined. The results show that, the nutrition in an apple in pericarp is higher than in pulp. The method can be applied to simultaneous determination of the content of Fe,Zn,Cu,Ca,Mg,Na,K in apple samples.
