氰化物镀铜液中铜的自动电位滴定

Automatic Potentiometric Titration of Copper in Cyanide Copper Bath

采用自动电位滴定法测定氰化物镀铜液中铜的质量浓度。实验结果表明:与常规的EDTA滴定法相比,用电极代替了常规法的指示剂来判定滴定终点,提高了分析的准确度和精密度,方法更为简便快捷。

The mass concentration of copper in cyanide copper bath was determined by automatic potentiometric titration method.The experimental results show that different from conventional EDTA titration method,it substitutes electrode for indicator used in conventional method to judge titration terminal,which can raise analytical accuracy and precision,and also easy and fast.
