摘要
采用空气-乙炔火焰原子吸收光谱法连续测定银锌电池材料用无甘油玻璃纸中铜、铁含量。介绍铜铁最佳测定条件及呈良好线性关系的浓度范围,并对样品消化处理条件及在样品测定中的干扰因素进行了考察。样品测定结果的相对标准偏差均小于1.0(n=10),加标回收率为98.0～98.5。该法适合生产现场控制分析和样品系统分析。
The contents of copper and iron in silver - zinc cell material were determined by air - acetylene flame atomic - absorption spectroscopy. Measurment conditions and affection factors were examined. The RSD was not more than 1.0% comparing to standard value. The standard adding recoveries were in the range of 98.0% -98.5%. The method is suitable for the controlling analysis and sample systems analysis.
