倒数示波计时电位滴定法

Reciprocal Oscillographic Chronopotentiometric Titration

提出了一种新的电滴定分析方法——倒数示波计时电位滴定法。它利用(dE/dt)^(-1)-E曲线上去极剂峰的出现或消失指示滴定终点,较经典示波滴定法灵敏,对(dE/dt)^(-1)-E曲线进行反对数非线性放大,则可以使终点峰形突变更加敏锐.

In this paper,a new method called reciprocal oscillographic chronopotentiometric titra-tion is presented.Because of its ability of decreasing charging current,the peak on (dE/dt)-1-E curve is more sharp than that of the corresponding incision on dE/dt-E curve and can be used to indicate the end-point of titration.
