摘要：
Kinetic data on Fe2O3 and Fe3O4 dissolution in solutions of hydrochloric and sulfuric acids of different concentrations are analyzed in terms of the chain mechanism model at different solution temperatures under different conditions of synthesis of oxide samples. A kinetic model of dissolution of iron oxides is proposed. It is shown that features of the iron oxide dissolution kinetics are explained by the difference between the concentrations of dislocations and other defects on the surface of particles.
