A method for determination of silicon, manganese, phosphorus, nickel content in new materials ferronickel by ICP-AES was established. The interference from matrix and co-existing elements was studied. The matrix effect was corrected by matrix matching. The analysis lines were Mn 293.930 nm, P 178.280 nm, Ni 231.604 nm, Si 251.611 nm. The detection limits of Si, Mn, P, Ni were 0.06, 0.04, 0.08, 0.04 mg/L, respectively. The relative standard deviation of determination results was below 5%, and the recovery was 95%-105%. This method is easy to operate with accurate results, and it is suitable for determination of Si, Mn, P, Ni contents in ferronickel.
