Abstract: The analysis method for determination of Na，Fe，Pb，Zn，Ca，Cr，Cd，and As in basic copper carbonate based on the inductively coupled plasma optical emission spectrometry（ICP-OES） has been presented.The determination conditions and operating parameters were researched.The yttrium standard solution internal standard method was used to remove matrix interference effect，and appropriate spectral line was selected to eliminate spectrum disturbance.Compare with atomic absorption spectrophotometry（AAS），this method had a faster analysis speed and a higher accuracy.

Key words: basic copper carbonate, ICP-OES, spectral interference, yttrium standard solution internal standard method
