摘要
文献提出用分光光度法测定大量铜镍铁存在下的铬,需经纸上色层分离,操作繁琐;容量法测定铬,共存元素有干扰,误差较大。本法介绍了在大量铁、镍、铜、锌等十几种离子存在下,不经分离,直接用火焰原子吸收法测定镀铬废水处理后泥渣中的总铬的分析方法。火焰原子吸收法测定铬影响因素较多,火焰状态,价态、共存离子等。
A mthod for determination of Cr in Cr-plating clay slag by air-acetylence flame atomic absorption specfrophotometry has been developed, Test Showed that in 1% sulfuric acid medium using sodium sulfite as reduce and interference-supperssion agents, the interference effeefs of a lat of Cu、Ni、Fe、Mg etc. ions Commonly occurred in samples could be dispel.
