经常的示波极谱滴定利用切口的出现与消失指示滴定终点。本文报导了一种示波极谱滴定的新技术,即通过电解池的交流电流很小,调节“■-E”曲线为一个固,利用整个示波极谱图的突然位移来指示终点。铂电极为极化电极,钨电极为对电极,甘汞电极为参比电极,观察铂电极对于参比电极的示波极谱图。 Frequent oscillographic titration uses the appearance of the incision and disappearance of the titration endpoint. This article reports a new technique for oscillopolarographic titration by means of a small AC current in the cell and adjusting the “-E” curve as a solid, using the sudden displacement of the entire oscillopolarogram to indicate the end point. The platinum electrode is a polarizing electrode, the tungsten electrode is a counter electrode, the calomel electrode is a reference electrode, and the oscilloscope polarography of the platinum electrode for the reference electrode is observed.
