提出用一氧化二氮 乙炔火焰原子吸收光谱法测定镉镍电池浸渍液中硅含量 .方法具有良好的灵敏度 ,干扰少 ,重现性好 .硅量在 5～ 5 0 μg/mL范围内与吸光度呈良好的线性关系 .其相对标准偏差均为 1.0 % ;标准加入回收率在 97.0 %～ 10 3.0 %范围内 ,适用于镉镍电池浸渍液中硅的分析 .

The application of nitrous oxide-ethyne flame ato mi c absorbing spectral method to measure the content of silicon in Cd-Ni batterie s impregnating solution is studied. The optimum measuring conditions for silico n and potency in which a fine liner range presents is introduced, and m akes a synthetic consideration to interference factors. The method has the advan tages of high sensitivity,And this method is proved, to be simple operation, ea sy master, short analyzing cycle, less interference and good in selectiv ity and reappearance. The relative standard deviations are all less than 1. 0 % in six s ample measures, and the standard adding recovery is the range of 97 %～103 % in six sample measures the practice shows that the method is fully suited to meas ure the silicon content in Cd-Ni batteries impregnating solution. The propose d method was proved to be a useful instrument analytical technique in nitrous ox ide-ethyne flame absorbing spectral method.
