Abstract

Abstract: Using expansion (contraction) and position shift of the whole oscillopolarogram to indicate the end-point of titration is a new technique which is a very useful oscillopolarographic titration method.This paper reports the principle of this method.The theoretical predictions consist with the experimental results.Expansion (contraction) of oscillopolarogram is due to the variation of electrode impedance and the position shift comes from the differences between kinetic factors at two electrodes.

Key words: Oscillographic titration, Oscillopolarographic titration, Oscillopolarogram
