Determination of Elements of Three Kinds of Vegetables

This article determined the content of five kind of element of three kinds of vegetables by flame atomic absorption spectrometry,the elements include calcium(Ca),copper(Cu),zinc(Zn),iron(Fe),manganese(Mn).The result showed that the content of five elements of leaf vegetable was higher than fruit vegetable and earth vegetable.The content of Ca and Zn in cole were higher than other vegetables,which were 7.6 g/100g and 8.98 mg/100g.The zinc content in leaf-used lettuce was the highest(16.72 mg/100g),the second was in spinach(12.63 mg/100g).And the iron content of spinach and leaf-used lettuce were 138.43 mg/100g and 111.1 mg/100g.The conclusion were that the content of Ca,Cu,Zn,Fe and Mn were higher in spinach,leaf-used lettuce and cole lettuce than other vegetables.
