| 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. |
