Role of complex formation in dissolution of
iron oxides in orthophosphoric acid
Abstract
The influence of the nature of acids on the
kinetic regularities of the dissolution of (hydr) oxide phases of iron in
acidic solutions was investigated. The nature of the potential-determining
reaction in the system magnetite electrode / orthophosphoric acid solutions was
determined. On the basis of experimental data, it has been shown that the
dissolution of iron oxide phases can be stimulated by influencing the potential
at the phase boundary between iron oxide / electrolyte solution.
Key words: (hydr) oxide phases of iron,
phosphoric acid, dissolution kinetics, potential-determining reaction.
