Electrochemical and Spectroelectrochemical Study of m-Phenylenediamine

Abstract

Abstract: Electrochemical and spectroelectrochemical properties of m-phenylenediamine(MPD) were studied by means of cyclic voltammetry and UV-Vis thin-layer spectroelectrochemistry. The cyclic voltammogram of MPD at gold disc electrode has an oxidative peak as well as a reductive peak. But at SnO₂;F film electrode, it has only an oxidative peak, which is an irreversible process. Potential-controlled UV-Vis thin-layer spectra of MPD at SnO₂;F film optically transparent electrode were recorded and a double logarithmic method was applied to treat the spectroelectrochemical data. From the double logarithmic plot, the kinetically modified formal potential E⁰=0.766 and αn=0.41 were obtained.

Key words: UV-Vis thin-layer spectroelectrochemistry, Cyclic voltammetry, Single potential-step chronoabsorptometry, m-Phenylenediamine
