微波消解-FAAS测定飞饿中钙、镁、铁、锌、铜和锰的含量

Determinations of Calcium,Magnesium,Iron,Zinc,Copper and Manganese in Fei E by FAAS with Microwave Digestion

采用微波消解-FAAS法对一种食用植物"飞饿"的叶和茎中铁、锌、铜、锰、钙、镁6种微量元素进行分析测定。结果显示飞饿中含有丰富的钙、镁、铁、锌、铜和锰元素。RSD为≤8.1%(n=6),加标回收率为94%—108.5%。

Six trace elements in the ＂Fei E＂ edible plant were determined by microwave digestion-FAAS method. The plant is aboudant of many essential elements such as Ca, Mg,Fe, Zn,Cu and Mn. The RSD（n = 6） is all smaller than 8. 1%, and the addition standard recovery （ASR, n= 6） are in the range of 94%-108.5% for all elements.
