Abstract：After the sample was digested with hydrochloric acid and nitric acid, micro amounts of impurities including Ti, W, Si, Mo, Co, Cr, Ni, Cu, Pb, Cd, As, Sn, P, Mn, Ca, Mg and Zn in 50 ferro-vanadium and 80 ferro-vanadium, and matrix Fe in 80 ferro-vanadium were simultaneously determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). The interferences of matrixes (Fe and V) and coexisting elements in sample were investigated. The analytical lines, background correction position and instrumental working parameters were optimized. The influence of matrixes (Fe and V) on sample solution atomization transmission, ICP equilibrium and excitation as well as determination was eliminated by combining matrix matching and synchronous background correction. The proposed method was used in the simultaneous determination of elements above in 80 ferro-vanadium. The results showed that the detection limit of the method was 5-55 μg/L, the background equivalent concentration was 5-95 μg/L, and the recoveries were 94 %-106 %. When the content of element was higher than 1.0 %, the RSD was less than 0.86 %. When content of element was between 0.001 % and 0.10 %, the RSD was less than 7.2 %. When the content of element was in range of 0.10 % -1.0 %, the RSD was less than 1.4 %. This method was applied to the determination of certified reference materials, and the found results were consistent with the certified values.
