摘要
A method was developed to determine of Fe, Al, Ca, Mg, Si, Mn, P, Ti, V, Co and Ni in chromite ore by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) with sodium carbonate and tetraborate melting. The amount of fluxes, detecting lines,instrument working parameters and matrix effects are discussed in this paper. Moreover, the effect of different amounts of Cr on the detection results was investigated, which indicates that Cr influences the detection results significantly. National Standard Reference Materials (GBW 07201, GBW 07202) were analyzed and the results that the recoveries were 91.4%～107.2%.
