不同茄子各部位中铁铜锰微量元素的测定

火焰原子吸收光谱法(FAAS)分别测定绿茄、紫茄不同部位中Fe、Cu、Mn三种微量元素的含量。结果:绿茄、紫茄不同部位中均含有上述三种微量元素,且含量存在差异,其中绿茄、紫茄各部位含量大小均为:FeMnCu,其中铁在两种茄子的皮、蒂部位中无显著差别,绿茄子肉中的铁含量高于紫茄子肉中的含量,在绿茄、紫茄相同部位中,绿茄子的锰元素含量较多;该实验的回收率在91.80%~105.30%之间,RSD1.60%,结果令人满意。

Each Part of the Different Eggplant Iron Copper and Manganese Determination of Trace Elements

The green tomato, Fe, Cu, Mn in different parts of the content of three kinds of trace elements were determined with flame atomic absorption spectrometry （ FAAS）.The results showed green , purple tomato and tomato were found in different parts of the above three kinds of trace elements , and had differences content , in which each part of the green eggplant , purple tomato amount were Fe 〉Mn 〉Cu, including iron in two eggplant skin and the place of no significant difference , the iron content of green eggplant meat was above the eggplant content in flesh , in green tomato, in the same place , the manganese content of green eggplant was more.The experiment of recovery rate was between 91.80%-105.30%, RSD〈1.60%, and the result was satisfactory.
