Electrochemical measurements on aluminium electrodes in acidic water/dimethylsulphoxide and acetonitrile solutions Available to Purchase

Introduction The electrochemical behaviour of metals and alloys in nonaqueous media are attracting considerable attention. The wide uses of metals in industry/research provide a great deal of information about their intensity in their alloys. Unfortunately little attention has been focused on aluminium. It has been reported that, on an aluminium electrode behaving actively and undergoing pitting corrosion in HCI solutions, an aluminium oxide film is never formed on the surface of the electrode during anodic oxidation. Therefore, aluminium electrodes have been studied in acidic HCI and H2SO4 dissolved in dimethylsulfoxide (DMSO) and acetonitrile (AN) and the results of this procedure have been compared with those of the behaviour of aluminium electrodes in an aqueous medium.
