利用自动电位滴定测重整催化剂中氯根含量,代替了伏尔哈德法,既提高了准确度又提高了效率。电位滴定分析氯时,以银电极为指示电极,甘汞电极为参比电极。指示电极上产生电位值的变化,将是在滴液和被滴液等当量浓度时为最大,滴定过程中随时记下指示电极的电位和滴液的加入量,可绘成滴定曲线,从而可查出测得的终点电动势。仪器借助一套电子放大系统和自动电磁阀门,使电极电位在到达终点电位的同时,滴液自动停止
The use of automatic potentiometric titration of catalyst reforming chloride content, instead of the Volkhad method, both to improve accuracy and improve efficiency. Potentiometric titration of chlorine, the silver electrode as the indicator electrode, calomel electrode as the reference electrode. The change of the potential value on the indicator electrode will be the maximum when the drop concentration and the equivalent concentration are dripped. The potential of the indicator electrode and the addition amount of the dripping liquid can be recorded at any time during the titration process, so that the titration curve can be plotted, Find the measured end point electromotive force. Instrument with a set of electronic amplification system and automatic solenoid valve so that the electrode potential reaches the end potential at the same time, the drip stop automatically
