Abstract：The method for the determination of Pb, Cd, Cr and Co released from ceramic ware by ICP-AES has been presented. The factors such as the influence of power in 4% acetic acid，the selection of analytical wavelength，and the interference of coexistent element have been investigated. The detection limits were 6.8 μg·L-1 for Pb, 0.18 μg·L-1 for Cd, 0.61 μg·L-1 for Cr, 1.0 μg·L-1 for Co. The recovery rates of the procedure were between 98% and 104%. The RSDs were between 0.27% and 1.24%. The method was simple, rapid, precise，convenient and suitable for daily inspection of import and export ceramic ware.
