Abstract：The yttrium-iron alloy sample was treated by nitric acid-hydrogen peroxide system. 103Rh and 185Re were selected as internal standard elements for the compensation and correction of matrix effect and measuring signal in 0.3mol/L nitric acid as determination medium. The determination of rare earth impurity elements in yttrium-iron alloy by inductively coupled plasma mass spectrometry (ICP-MS) was realized. The mass spectrometry interference was eliminated by selecting proper isotopes and interference correction equation. The dilution factor was 2000. In other words, the mass concentration of matrix was controlled at 0.5mg/mL to eliminate the influence of matrix effect. Under the optimized experimental conditions, the linear correlation coefficients of calibration curves for 14 rare earth elements were all higher than 0.9999. The detection limits of elements were between 0.003μg/L and 0.020μg/L. The experimental method was applied for the determination of rare earth impurities in yttrium-iron alloy sample. The relative standard deviations (RSD, n=11) of determination results were between 0.97% and 6.5%, and the spiked recoveries were between 96% and 104%. The yttrium-iron alloy sample was determined according to the experimental method. Meanwhile, the inductively coupled plasma atomic emission spectrometry (ICP-AES) combined with matrix matching method was also adopted for comparison. The determination results of two methods were basically consistent.
