摘要：

The effect of propargyl alcohol (PA) on iron dissolution reaction in deaerated hydrochloric acid was studied by several electrochemical methods. Results of quasi-steady-state polarization measurements showed that PA strongly influences the chloride-involving dissolution reaction proceeding at lower anodic potentials. The values of polarization resistance and double-layer capacitance obtained by analysis of impedance spectra indicate a change of protective properties of an organic protective film with time. The impedance spectra taken at three different anodic potentials showed the potential dependence of adsorption/desorption process of electroactive intermediates.
