Abstract: Inductively coupled plasma atomic emission spectrometry was adopted to determine iron, silicon and aluminum elements in vanadium. Analysis spectral lines and working parameters of the instrument were optimized. Nitric acid and hydrochloric acid were used to dissolve the sample, and the matrix matching method was applied to eliminate the interference of elements.Relative standard deviation was no higher than 2.57%, and the recovery was between 95.6%~114.0%.
