摘要
经典的示波计时电位滴定法是利用用dE/dt-E曲线上去极剂切口的出现或消失指示滴定终点,其优点是仪器简单、终点直观、准确快速,不足之处是有些去极剂在示波计时电位图上的切口不敏锐,当被测物含量较低,或用较低浓度的滴定剂进行滴定时。
The technique of feeding back current is applied to the reciprocal oseillographie chronopotentiometrie titration. Thus the capacity current can be greatly deducted and the sensibility of titration is enhanced If the feeding back current reciprocal oscillographic chronopotentiomerie curve is treated by differentiation, the sensibility of the titration will be sharply improved,
