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。
This paper presents the photometric titration of copper with EDTP at 510 nm with 5-Cl-PADAB as an indicator in a pH 5.5 aqueous solution. The end of this method is fast response and high selectivity, suitable for titration of 5 ~ 2000μg copper, has been used for the determination of copper in lead alloy, aluminum alloy and zinc alloy.
