The oxidation of phenothiazine in dilute solutions of sulphuric acid leads to the corresponding cation radical. Using a potentiometric technique, a pKa value of 5.72 ± 0.05 was determined for phenothiazine. The kinetics has been studied and participation of both protonated and unprotonated oxidant in the oxidation reaction has been confirmed. Using a voltammetric technique with a rotating disk electrode, the anodic oxidation of phenothiazine was shown to be a one-electron diffusion-controlled process. A quantum chemical explanation was found for the direction of phenothiazine protonation and the absence of a dimerization stage of oxidation.

This work was to study the dissolved CO in solution phase by using rotating disk electrodes and the solution phase CO demonstrate the limiting currents dependence of rotating speeds. Gold and gold-platinum metals clusters are used in glassy carbon supported rotating disk electrode for electrochemical oxidation of the solution phase CO. Small metal clusters and Au-Pt alloy effects are observed in the measurements. The comparison of microelectrode and RDE study of solution phase CO electrochemical oxidation is confirmed the limiting currents dependence of the boundary layers concentrations.
