Abstract：Cerium-iron alloy was a kind of additive for rare earth steel, and it played an important role in enhancing the performance of rare earth steel products. The rapid and accurate determination of aluminum, silicon and nickel in cerium-iron alloy has great significance for the quality control of products. The sample was dissolved with hydrochloric acid and nitric acid. Al 396.153nm, Si 251.612nm and Ni 231.604nm were selected as the analytical lines. The matrix effect was corrected by matrix matching and blank correction. The content of aluminum, silicon and nickel in cerium-iron alloy was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). The calibration curves of elements were linear when the mass fraction was in range of 0.0050%-0.20%, and the correlation coefficients were all higher than 0.9999. The detection limit of aluminum, silicon and nickel for method was 0.0012%, 0.0006% and 0.0003%, respectively. The proposed method was applied for the determination of aluminum, silicon and nickel in cerium-iron alloy. The relative standard deviations (RSD, n=11) of results were less than 7%, and the recoveries were between 90% and 115%. The content of aluminum, silicon and nickel in cerium-iron alloy was determined according to the proposed method. Meanwhile, the content of silicon was also determined by spectrophotometry, and the content of aluminum and nickel was determined by inductively coupled plasma mass spectrometry (ICP-MS). It was found that the determination results were consistent for different test methods.
