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.
