摘要
用HClO4-HNO3混合酸液(体积比为4∶1)消解样品,采用电感耦合等离子体—原子发射光谱法(ICP-AES)测定了新高梨花粉中K、Na、Ca、Mg、Zn、Cu、Fe、Mn 8种矿质元素的含量.结果表明:在试验范围内各元素线性关系良好,回收率在97%～103%,RSD值在0.74%～1.79%,具有较高的准确度和精密度.新高梨花粉中含有丰富的K、Ca、Mg、Fe、Na、Zn、Cu、Mn,在元素含量上K>Ca>Mg>Fe>Na>Zn>Cu>Mn.
The contents of mineral elements such as K,Na,Ca,Mg,Zn,Cu,Fe,Mn,in Xingao pear pollen was tested by coupled plasma atomic emission spectrometry（ICP-AES）.The results showed that linear relationships for different elements are good,the range of recovery is between 97% and 103%,the RSD is between 0.74% and 1.79%,which have a good precision and accuracy.The Xingao pear pollen are rich in mineral elements such as K,Ca,Mg,Fe,Na,Zn, Cu,Mn.The contents of elements are K＆gt;Ca＆gt;Mg＆gt;Fe＆gt;Na＆gt;Zn＆gt;Cu＆gt;Mn.
