摘要： 建立了同时测定一次性纸杯中Cu,Mn,Fe,Zn,K,Mg,Ca,Cr,Hg和Pb等10种微量元素的电感耦合等离子体发射光谱(ICP-OES)法。实验结果表明:方法线性关系良好,相关系数在0.991~0.999之间,线性范围较宽,操作简便。采用该法对10种品牌一次性纸杯(无油墨部分)中微量元素进行检测表明:无油墨部分的纸杯中含有丰富的K,Mg和Ca等有用元素,同时也含有Zn和Fe等人体必需的微量元素;Cu,Mn,Fe,Zn和K质量浓度分别为1.02~24.15,0.003~2.77,9.16~52.56,0.39~1.62和2.17~15.91 mg/L;品牌3,5和7纸杯含有Pb;品牌3,4和5纸杯含有Hg;品牌7纸杯Cr和Cu含量最高。

Abstract: A method for simultaneous determination of ten kinds of element Cu,Mn,Fe,Zn,K,Mg,Ca,Cr,Hg and Pb in disposable cups by inductively coupled plasma atomic emission spectroscopy (ICP-OES) was established.Experimental results showed that the method displays good linear relationship with correlation coefficient between 0.991~0.999;and the linear range is quite wide.Meanwhile,the operation is simple.By measurement of ten kinds of disposable cups (no printing ink part) with the ICP-OES,the results showed that some disposable cups contain rich useful elements,such as K,Mg and Ca,as well as essential trace elements for mankind,such as Zn and Fe et al.The mass concentration of Cu,Mn,Fe,Zn and K are 1.02-24.15,0.003-2.77,9.16-52.56,0.39-1.62 and 2.17-15.91 mg/L respectively.However,disposable cup item 3#,5# and 7# contain Pb;item 3#,4# and 5# contain Hg.Among all items,item 7# contains both Cr and Cu at a relatively highest level.

Key words: inductively coupled plasma atomic emission spectroscopy, disposable cups, metal elements
