Sažetak
The aim of this work is to study the influence of iodide ions on the adsorption of azole inhibitors on copper in hydrochloric acid. The inhibiting efficiency of different azole compounds was studied (benzotriazole, benzimidazole, 1-(p-tolyl)-4-methylimidazole and 1-phenyl-4-methylimidazole). Investigations were performed through electrochemical polarization measurements and electrochemical impedance spectroscopy. Our study has confirmed the synergism of investigated azoles and iodide ions. The degree of synergism and the structure of the protective layer depend on the molecular structure of the azole compound. Although both the benzotriazole and studied imidazole compounds are mixed-type inhibitors, in the presence of iodide ions, the benzotriazole behaves as a predominantly anodic inhibitor, while imidazoles behave as predominantly cathodic-type inhibitors. The difference in the corrosion inhibition mechanism can be explained, based on the difference in molecular structure of investigated azoles.
