摘要
利用HNO3/H2O2湿法微波消解制样、再应用全谱直读电感耦合等离子体原子发射光谱法(ICP-OES),对胡萝卜中的矿物元素组成进行全面的分析与测定。定量分析了K、Ca、P、Na、S、Mg、Al、Si、Ba、Zn、Fe、Sr、B、Cu、Mn、V、Pb、Cr、Ti等19种矿物元素,定量结果相对标准偏差在0.15%~10.3%之间,标准样品回收率测定在89.0%~109.6%之间。实验结果可为胡萝卜的应用研究提供基础数据。
By wet microwave digestion procedure with HNO3/ H2O2to prepare samples,the mineral elements in carrot were detected and analyzed thoroughly by inductively coupled plasma optical emission spectrometer( ICP-OES). The results showed that there were 19 mineral elements in carrot,which are K,Ca,P,Na,S,Mg,Al,Si, Ba,Zn,Fe,Sr,B,Cu,Mn,V,Pb,Cr and Ti. The RSD of results was between 0. 15% and 10. 3%. The recovery rate of standard sample was from 89. 0% to 109. 6%. These results provided basic data for further developing and applying of carrot.
