摘要
本文提出在pH5.5水溶液中,在510nm处,以5—Cl—PADAB为指示剂,用EDTP光度滴定铜。本法的终点响应迅速,选择性高,适用于滴定5～2000μg铜,已用于铅合金、铝合金和锌合金中铜的测定。
In this paper, the spectrophotometric titration of copper with EDTP using 5-C1-PADAB as indicator has been reported at pH 5.5 aqueous solution and 510 nm. The end point is sharp. The method is selective and suitable for the titration of 5～2000μg of copper. It has been applied to determine copper in lead alloys, aluminium alloys and zinc alloys.
