The contents of trace elements of Ag, Cu, Zn, Fe, Pb, Sb and Bi in gold foil were determined directly by ICP-AES method and the gold content of gold foil was calculated. The authors obtained optimal working parameters of the instrument and studied the selections of power in analytic conditions and analytic curve, the optimization of the pressure of nebulizer as well as the influence of lifting capacity of the sample.
