A method for the determination of three elements—copper, aluminum and phosphorus in ferroniobium by inductively coupled plasma atomic emission spectrometry (ICP-AES) was studied. In the experiment, the sample is decomposed by nitric acid and hydrofluoric acid. Sulphuric acid was added to heat for smoking. Then citric acid was added. After constant volume, the sample was determined under optimal spectral lines and proper working conditions. The determined result shows that this method is simple, rapid and sensitive, with the detection limit between 0.004% and 0.009%, and the linear range is wide. The deviations were less than that of the standard deviations. Recovery rate was between 96% - 104%.
