摘　　要：建立了电感耦合等离子体-原子发射光谱法(ICP-AES)同时测定蜂蜜中Na、K、Mg、Ca、Sr、Ba、Mn、Fe、Cu、Zn、Al、Se、Ni、Li、V、Cr、Co、Cd、As和Bi 20种微量元素的分析方法。样品无需消化,直接用硝酸溶解,配成稀酸溶液,上机测定。20种元素的加标回收率为75.2%～110%,相对标准偏差(RSD)<7.00%,方法检出限在0.0038～0.29mg/kg之间。将该法应用于野生蜂蜜、桂花蜜、冠生园蜜、洋槐蜜、紫云英蜜及汪氏蜂蜜中的微量元素的测定,发现蜂蜜中含有丰富的Na、K、Mg、Ca、Se、Fe、Zn、Al等微量元素,不同品种之间含量差别较大;蜂蜜中有害重金属的含量很少,符合食品中重金属的限量标准,Cd、Cr、As、Bi在6种蜂蜜中均未检出。A simple and accurate method for the simultaneous analysis of 20 trace elements（Na,K,Mg,Ca,Sr,Ba,Mn,Fe,Cu,Zn,Al,Se,Ni,Li,V,Cr,Co,Cd,As and Bi） in honey by inductively coupled plasma-atomic emission spectrometry（ICP-AES） has been developed.The average recoveris of the 20 elements were between 75.2%～110%,the relative standard deviatioms（RSDs） were lower than 7.00%,and the limits of detection were between 0.0038～0.29 mg/kg.The method was applied to the simultaneous determination of 20 elements in six kinds of honey（wild honey,osmanthus honey,guan shengyuan honey,chinese milk vetch honey,acacia honey and wang＇s honey） with satisfactory results.The results showed that the honey is an excellent source of K,Mg,Ca,Se,Fe,Zn,Al and other trace elements.The contents of trace elements in different kinds of honey are different.The contents of harmful metals are lower than the food standards for harmful heavy metals,and Cd,As and Bi were not detected in the six samples.
