| Abstract | A refined scheme of iron anodic dissolution in acidic sulfate solution, in which Fe0 is oxidized to Fe+ in stages, is proposed. The first stage consists in chemisorption of H2O molecules with participation of SO42– anions; the degree of the participation x ≈ 0.5 per a water molecule. This stage produces adsorbed OH groups (Fe(OH)ads), which, as a result of their interaction with sulfate anions, form an adsorption complex Fe((OH)SO42–ads. The schemes of oxidation of Fe+ to Fe2+ do not differ from conventional ones. The scheme put forward agrees with the literature data on the kinetics of iron dissolution under steady-state conditions. |
