摘要
本文提出了在碘量法分析铜中对引起终点判定误差的常见干扰物的消除方法,讨论了碘化钾的加入问题并对大量碘化钾的加入不妨碍对滴定终点判定的观点进行了验证.
This article put forward ways to eliminate the common interference in iodine quantity Cu-analysis that causes misjudgment at final stage, and discusses the issues of addition of potassium iodide and assesses the point of view that large amount of potassium iodide addition would not impact on the final titration determination.
