摘　　要：用Air-C2H2火焰原子吸收光谱法测定银锌电池醋酸纤维素膜中铁含量。介绍了样品的消化处理条件和铁最佳测定条件,铁浓度0—10μg/mL范围内呈良好线性关系。该方法的灵敏度好,准确度与精密度均能满足银锌电池研制工作的要求。测定样品中铁含量相对标准偏差均小于1.0%(测定次数n=6)。标准加入回收率均在97.3%—98.0%(n=6)范围。适用于银锌电池醋酸纤维素膜中铁的测定。The amount of ron in cellulose acetate membrane of silver-zinc cell was determined by Air-C2H2 flame atomic absorption spectrometry. The measuring conditions were optimized, and interference factors were also considered. The method is sensitive, selective with the relative standard deviations less than 1.0% （n= 6） in six sample measures, and the standard adding recovery are in the range of 97.3%-98.0%.
