众所周知,在酸性镀铜液中氯离子也是一种不可缺少的光亮剂。但测定氯离子的方法很多:比色测定法、选择性电极法、硝酸汞滴定法、硫氰酸钾回滴法等。但有些比较麻烦,有些终点极不明显很难测出准确值。作者在生产实践中用硝酸银滴定对比法很容易快速了解氯离子大概含量的范?..
It is well known that chloride ion is also an indispensable brightener in acid copper plating solution. However, many ways to determine chloride ion: colorimetric assay, selective electrode method, mercury nitrate titration method, potassium thiocyanate back drop method. However, some are more troublesome, some of the end-point is very difficult to measure the exact value. The author in the production of silver nitrate titration with contrast method is easy to quickly understand the approximate content of chloride ion range?
