      运用空气-乙炔火焰原子吸收光谱法同时测定银锌电池三醋酸纤维素膜中铜铁含量,并对测定条件和干扰因素进行了综合分析.该测定方法具有很好的灵敏度,干扰少,选择性和重现性好等优点.测定样品铜铁含量的相对标准偏差均小于1.0%.标准加入回收率均在97.3%～98.8%范围内.完全适用于银锌电池三醋酸纤维素膜中铜铁含量的控制和样品系统分析.

英文摘要:

      The measure of copper and iron content in three cellulose acetate membrane of the zinc-silver battery by using the AIR-C₂H₂ flame atomic-absorption spectroscopy and make synthetically consideration of the measuring conditions and factors were atuded. The method possesses many advantages such as high sensitivity and accuracy, less interference and good repeatability and selectivity. The deviation RSD1.0% comparing to standard value. The standard adding recovery is in the range of 97.3%～98.8%. The proposed method fully suited to the control of copper and iron content in Three cellulose acetate membrane of the zinc-silver battery and to the analysis for sample system with good effect.
