英文摘要By comparing the methods of matrix matching and standard addition and multi-spectral fitting ( MSF) for elimination of interference, an analytical method for the determination of trace cobalt in high purity nickel by inductively coupled plasma atomic emission spectrometry (ICP-AES) was established. The optimum parameters of the instrument were determined as follows: RF power of 1350 W, atomizer velocity of 0.5 L/min, observation distance of 15 mm, and peristaltic pump speed of 1. 0 mL/min. Three calibration methods, matrix matching, standard addition and MSF, were used to determine the standard addition of pure nickel solution. When the standard addition concentrations were 0. 10 and 0. 20 mg/L, and nickel concentration was 5 g/L, the three methods all could get good recovery. The linear correlation coefficients were all greater than 0.9996, the recoveries were 95.0% -102.0%, and the RSDs were 2. 1% -4.6%. The linear range of MSF method was the best ( 0. 02 - 0. 5 mg/L) and the detection limit was the lowest (0.002 mg/L). When the standard addition concentrations of nickel were 0. 02 and 0. 06 mg/L and the nickel concentration was 15 g/L, the results showed that only the MSF method could get accurate results with linear correlation coefficient of 0. 9999, linear range of 0. 02 -0. 1 mg/L, detection limit of 0. 002 mg/L, recoveries of 95.0% -105. 0%, and RSDs of 3. 9% -4. 6%. The MSF method was used to test the actual samples. The analytical results were 0. 000154%, which was consistent with the GD-MS method. The RSD was 2. 3%. The accuracy and precision of the method were further verified. MSF method is not only strong in anti-interference, simple in operation, economical and practical, but also has high precision, low detection limit. The lower limit of detection (0. 0001% ) and detection range are superior to the national standard atomic absorption spectrometry (0. 001%). It provides an important methodological method for the determination of trace impurities in high-purity samples.
