Cyclic voltammetry is widely employed in electroanal.studies because it provides fast information about the redox potentials of the electroactive species and the influence of the medium on the redox processes. Azole compoundshave been found to be effective corrosion inhibitors for copper in chloride-containingsolutions The aim of this work was to investigate in detail the influence of the addition of various azole compoundson the oxidationmechanism of copper in chloride-containingsolutions, using cyclic voltammetry. The influence of thirteen azole compounds, at three different concentrationson the electrochem./ chem. reactions of pure copper immersed in 3 weight% NaCl solutionwas studied using cyclic voltammetry at different scan rates. The change of the peak current and potential with the scan rate were investigated. The possible linearity was compared with the theor.derived mechanism. The possible reaction mechanisms were discussed based on the linearity of these parameters (peak current and potential) with the scan rate compared to theor.derived models. Both the peak current and peak potential of the copper samples immersed in chloridecontaining solutionswith additionsof the majority of azole compoundsshowed linearity with the square root of the scan rate, suggesting that copper follows the Muller-Calandra passivation model. The same behavior was also found for copper in chloride-containing solutions without additionsof azole compounds A linear variation of the peak potential with the natural logarithm of the scan rate and linear variation of the peak potential with the square root of the scan rate was observed for the copper samples immersed in chloride-containing solutions with the addition of 10 mM of 2-mercapto-1- methylimidazole, imidazole, or 2-aminobenzimidazole. This suggests that copper follows irreversible redox reactions under a diffusion controlled process. No other linear relations of the peak current and peak potential with the scan rate were found. Copper oxidationin chloride-containingsolutionsis controlled by passivation (following the Muller-Calandra passivation model) upon the addition of the majority of the selected azoles. In the minority of cases, irreversible redox reactions that follow a diffusion-controlled process were identified. None of the systems followed an adsorption-controlled process. Moreover, none of the tested systems underwent reversible redox reactions that followed a diffusion controlled process. In the part of experimental materials, we found many familiar compounds, such as 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Electric Literature of C7H7N3)
1H-Benzo[d]imidazol-2-amine(cas: 934-32-7) can be used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles.Electric Literature of C7H7N3
