摘　　要：采用N2O-C2H2火焰原子吸收光谱法测定镍氢电池铂黑中的镍，方法的精密度和准确度高，具有操作简便、快速、重现性好、容易掌握等特点。测定质量浓度为9．42mg／L的镍．相对标准偏差均小于0．5％，加标回收率均在97．0％～98．5％，结果与认定值相符。本方法适用于铂黑中镍的生产现场控制分析和样品系统分析。The application of N2O - C2 H2 flame atomic absorption spectrophotometer for the determination of nickel in platinum black of Ni - MH battery was studied. This paper introduces the optimum measuring conditions for nickel and potency in which a fine liner range presents. Under the condition of the determi- nation of 9.42 mg/L Ni content, the relative standard deviations are all less than 0.5% in six sample measures, and the standard adding recovery is in the range of 97.0%～98.5%. This method is fully suited to measure the nickel in platinum black.
