    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 microg x L(-1) for Pb, 0.18 microg x L(-1) for Cd, 0.61 microg x L(-1) for Cr, 1.0 microg x 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.
