The application of nitrous oxide-ethyne flamic absorbing spectral method to measure the content of Si in positive impregnating solution of Ni-Cd batteries was studied. The optimum measuring condition for Si and potency in which a fine liner range presents and makes a synthetic consideration to interference factors were introduced. The method had the advantages of high sensitivity, less interference and good in selectivity and reappearance. And this method was proved to be simple operation, easy master, short analyzing cycle. The relative standard deviation was less than 1.0% (n=8), in eight sample measures, and the standard adding recovery was in the range of 97.0%～103.0% (n=5). The results show that the method is suited to measure the Si content in positive impregnating solution of Ni-Cd battery. The proposed method is proved to be an useful instrument analytical technique in nitrous oxide-ethyne flamic absorbing spectral method.
