Аннотация
The Pourbaix diagrams of the systems SO42−−SO32−−H2O and iron hydroxide (oxide)–H2O are refined. The E(pH) dependence of the sulfitization of iron(III) hydroxide is refined with allowance for the regions of predominant phase constituents of the systems. The potential E–pH electrochemical equilibrium diagrams of the systems Fe(OH)3–H2SO4–SO32−–H2O, FeOOH–H2SO4–SO32−–H2O, and Fe2O3–H2SO4–SO32−–H2O are plotted. These diagrams can be considered as a thermodynamic basis for the sulfite conversion of the ferrous cake of copper–nickel production.
