| Abstract: | The application of nitrous oxide-ethyne flame atomic absorption spectrum to research of Iron content measurement in copper-silver alloy of cadmium nickel battery is studied. This paper introduces the optimum measuring conditions for Iron content and potency in which a fine liner range presents. The method has the advantages of high sensitivity, less interference and good in selectivity and reappearance. The relative standard deviations are all less than 1.0 %（n=10） in ten sample measures, and the standard recovery is in the range of 97.0 %-99.0%. |
