利用示波极谱图上切口的出现或消失来指示滴定终点的示波极谱滴定法具有终点直观、操作简便、仪器简单和抗干扰能力强等优点,但此法要求试剂能在示波极谱图上产生敏锐的切口。在微铂电极和铂片电极上进行示波极谱氧化还原滴定时,人们往往看到在滴定终点整个示波图发生突然变化,这种变化包括整个示波图的骤然扩大或缩小以及示波图位置的骤然移动。这种整个示波图的变化如此突然、灵敏,完全可用来指示滴定终点。在这里并不要求试剂在示波极谱图上产生切口。这个现象Stefanovic等早在1968年
The use of oscillographic polarographic incision on the appearance or disappearance of the end point to indicate the titration oscilloscope polarographic titration has an intuitive endpoint, easy to operate, the instrument is simple and strong anti-interference ability, etc., but this method requires reagents in the oscillopolar Sharp incisions on the spectrum. When oscillopolarographic redox titration is performed on micro platinum electrode and platinum electrode, people often see sudden changes in the entire oscillogram at the end of titration. Such changes include sudden expansion or contraction of the entire oscillogram and oscillography Suddenly move the map position. The whole oscillogram changes so suddenly, sensitive, completely available to indicate the end of the titration. Reagents are not required here to generate incisions on the oscilloscope polarography. This phenomenon Stefanovic et al as early as 1968
