The anodic dissolution of pure iron in acetonitrile-water solutions with varying concentrations of acetonitrile and varying pH has been investigated. Potentiodynamic measurements with different sweep rates have been done. Acetonitrile was shown to act as an interface inhibitor for the dissolution of
In the presence as well as in the absence ofacetonitrile the hydrogen evolution reaction was found to follow a Volmer-Heyrovsky mechanism with a minor contribution from the Tafel reaction in parallel. Contribution from surface diffusion between equally spaced step lines were found in both cases. The
Iron microelectrodes have been used to study the dissolution kinetics in acidic perchlorate solutions, in the absence and in the presence of acetonitrile. The results compare well with previous measurements on a conventional sized rotating disc electrode. The advantages of using microelectrodes are
