摘　　要：以微波消解法对不同品种柑橘样品的果皮和果肉分别进行处理,采用火焰原子吸收光谱法测定了其中Ca、Mg、Fe、Mn、Cu、Zn等6种人体必需的微量元素含量。实验结果表明,柑橘的果肉和果皮中含有十分丰富的微量元素,各元素的加标回收率在93.0%—113.3%之间,相对标准偏差≤4.5%,测定方法简便、快速、准确。The contents of six trace elments of peels and pulps in different varieties citrus, including Ca, Mg, Fe, Mn, Cu, Zn, were analyzed by FAAS with microwave digestion. The results showed that the trace elements which were necessary to human were rich both in peels and pulps,the recoveries of elements were in the range of 93.0%-113. 3% ,with the RSD≤4.5%. The method is simple,rapid and accurate.
