摘要: West等人[1-2]首先研究了镉、钴、铬、铜、铁、锰、镍、铅等金属离子和某些有机化合物在铂电极上的吸收光谱电化学特性,并导出定量分析公式,但迄今为止,此法还未用于实际样品分析。本文在以前工作基础上,用原子吸收分光光度计,着重试验了钠、钙、镁、铝等对铜的影响,直接测定了腐蚀剂和氯化钠中的铜,获得了良好的结果。

Abstract: The interference effects of sodium,calcium,magnesium and aluminium on the determination of copper were examined.The results show that the presence of 5000ppm Na+,500ppm Ca2+,100 ppm Mg2+,in the analyte solution has no influence on the determination,the interference of aluminium on the copper is serious.The copper in corrosive and sodium chloride was determined directly.The results are satisfactory.
