Abstract: A method for the determination of Sb, As, Bi, Sn, Zn and Fe in leadantimony alloy by inductively coupled plasma-atomic emission spectrometry was established. The determination condition was tested and optimized. Interference from matrix effect and from interelement was studied. Spectral interference and background correction methods were also proposed. The detection limits of the method were 0.002～0.03 mg/g for these elements and the recovery was 95.5%～105.0% with the precision of <2%RSD（n＝12）. The method has been applied to the determination of these elements in leadantimony alloy with satisfactory results.
