Abstract
Diphenylethylarsine has been tested as a corrosion inhibitor for electropolished zinc in perchloric acid solution, using weight loss and polarization methods. The corrosion of zinc is reduced by 85% in the presence of 2 × 10 -4M diphenylethylarsine. Anodic and cathodic polarization data reveal that diphenylethylarsine acts as an interfacial corrosion inhibitor for zinc in acidic solution. The free energy of adsorption of diphenylethylarsine is reported for different concentrations of solution.
