Abstract

The problem of the corrosion in acidic and aqueous media, primarily on metals of the “iron” group, has evoked numerous studies related to the discharge of hydrogen cations. It has been shown that inhibitor adsorption can noticeably affect the process of hydrogen evolution during corrosion of metals with hydrogen depolarization. Such inhibitors include pyridine, which is present in zinc electrolysis solutions. As it was shown earlier, pyridine negatively affects the current efficiency of zinc and the quality of the cathode metal. We studied the electrochemical reduction of hydrogen (hydronium ion) from acidic aqueous solutions in the presence of a surfactant (pyridine on a zinc cathode). The electroreduction of hydrogen cations was studied under conditions of intense mixing using a magnetic stir bar that removed gas bubbles from the cathode surface. The studies were carried out in solutions of sulfuric acid grade OSCh (0.9; 0.18; 0.36 M) with the addition of pyridine from 1.4 to 8.4×10–3 M. Potentiostatic studies were carried out on a potentiostat “P-30Jcom Elins” using a three-electrode cell. In potentiometric measurements, the results are presented according to the average data obtained over 30 s of electrolysis in the potential range (–950 to 1100 mV for AgCl/Ag). In galvanostatic measurements at current densities from 0 to 110 mA/cm2, the results are presented by average data obtained in initial 5 s of the process. It is shown that with an increase in the content of sulfuric acid in the electrolyte and the cathode potential, the current density increases. When pyridine was added to the electrolyte, a decrease in the cathode current density was recorded, as in earlier studies on the electroreduction of zinc in the presence of the above organic matter. Moreover, the deceleration of the hydrogen discharge with the addition of pyridine increased with an increase in the acidity of the electrolyte and the cathode potential. We calculated the order of the discharge reaction by hydroxonium ions. This allowed us to make an assumption that the process is characterized by mixed kinetics with the initial stage of obtaining atomic hydrogen according to the scheme: H3O+ e– → H0 + H2O. The decrease in the order of the hydrogen reduction reaction with the addition of pyridine is explained by the transformations that occur with this compound during electrolysis.
