| 摘 要： | 目的:运用火焰原子吸收光谱法直接测定了甘南地区三个不同采集地的鲜卑花属植物叶中锌(Zn)、铜(Cu)、锰(Mn)、铁(Fe)、钴(Co)、镍(Ni)、镁(Mg)七种微量元素的含量.方法:用混合酸硝化样品,采用标准曲线法测定.结果:所测定的三个不同采集地中含有的人体必需微量元素略有差异.结论:本方法简单、准确,回收率在96.8%～102.3%之间,相对标准偏差(RSD)在0.78%～2.15%之间,结果令人满意.

| Abstract: | Seven trace element contents including Zn,Cu,Mn,Fe,Co,Ni,Mg in Sibirae were directly analyzed by flame atomic absorption spectroscopy.The sample was nitrated with mixed acid.The method is simple and rapid by calibration curve method.The results indicate that the measured content of inorganic elements has obviously regional difference.The recovery rate is 96.8%-102.3% ,RSD 0.78%～ 2.15%.The results are accurate and satisfactory. |
