Abstract
The effect of the nature of acids on the kinetic regularities of the dissolution of iron (hydr) oxide phases in acidic solutions is studied. The nature of the potential-determining reaction in the magnetite electrode/orthophosphoric acid solutions system is revealed. It is shown based on the experimental data that the dissolution of iron oxide phases can be stimulated varying the iron oxide/electrolyte solution phase-boundary potential.
