摘　　要：运用N2O-C2H2火焰原子吸收光谱法进行镍氢蓄电池材料用氧化锆布膜中铝含量的分析测试技术,建立了铝的共振线、灯电流、火焰燃烧比等最佳实验条件.显示出该方法具有很好的灵敏度和重现性,具有操作简便、容易掌握、分析周期短、干扰小等优点.测定样品铝含量的相对标准偏差均小于1.0%(n=6).标准加入回收率均在97.5%～98.6%范围内.适用于镍氢蓄电池材料用氧化锆布膜中铝含量的控制分析和样品系统分析.The application of nitrous oxide - acetylene flame atomic absorption spectrometer to analyze the aluminum content in the zirconium oxide cloth film of hydrogen - nickel battery is studied. The optimum conditions for measuring the aluminum content are established. The method has the advantages of high sensitivity, less interference and good in selectivity and reappearance. The relative standard deviation＇s are less than 1.0% （ n =6） in six sample measurements, and the standard adding recovery is in the range of 97.5% - 98.6% （ n = 6 ）. This method is suitable for the quality control of the aluminum content in the zirconium oxide cloth film in the hydrogen - nickel battery and systematic analysis of the sample.
