- Аннотация: With the cycling of potential step, the dissolution rate of iron is shown to decrease with an increase in the degree of its surface coverage with hydrogen atoms. With a bipolar electrode (a membrane), an increase in the concentration of hydrogen in the metal phase was found to decelerate the anodic dissolution of iron in a base sulfate electrolyte and accelerate it in the presence of thiocyanate ions. The latter phenomenon indicates the possibility of activating the ionization of iron with the hydrogen dissolved in it. The rate constants of individual stages of the cathodic evolution of hydrogen are calculated.
