摘要
在酸性介质中,以银复合电极为测量电极,由二阶微商法确定滴定终点,根据消耗的硝酸银标准滴定溶液体积测定铜电解液中的氯量。通过对仪器条件设置、基体影响、储存温度等试验,确定了准确测定方法。该方法合理有效、准确度高;且耗时短、易操作,具有其他方法无法比拟的优势。
In acidic medium, with silver composite as measuring electrode, chlorine content in copper electrolyte is calculated by using the second order micro commercial determine the titration end point, according to the consumption volume of standard titration solution of silver nitrate. The accurate determination method is determined by setting instrument condition, changing matrix, storage temperature test, etc. The method has the incomparable advantages of reasonable and effective, highly accuracy, short time-consuming and easy to operate over other methods.
