Fiftieth Anniversary: A Brief Summary of Hydrogen Electrode Kinetics

The dissolution of mild steel by warm sulphuric acid with and without organic inhibiting additions has been studied by means of simultaneous measurements of corrosion rate and corrosion potential, and by the determination of true anodic and cathodic polarization curves in the neighbourhood of the natural corrosion potential.Quinoline, 2 : 6-dimethylquinoline, a-and p-naphthoquinolines, N-ethylquinoline, thiourea, methylthiourea, ethylthiourea and 0-, m-and p-tolylthioureas inhibit the dissolution of mild steel by 5% (w/v) sulphuric acid at 70" and 40", being increasingly effective in the order given above. The quinolines are primarily anodic inhibitors, but at high concentrations they limit the cathodic reaction also; the thioureas inhibit both cathodic and anodic reactions, the cathodic the more at low concentrations, the anodic the more at high.The results are interpreted by a modified adsorption theory and are discussed in terms of recent fundamental views of electrode reactions. Some practical implications are pointed out.
