| Abstract Scope |
Experiments were carried out in NaOH-H2O (50-50 wt%) electrolyte with a suspension of Fe2O3 particles at ~100 o C. A rotating disk electrode of graphite or silver was used as the cathode. The current efficiency for iron deposition was consistently higher than 90 %. Recent experiments were carried out by using iron containing residue from industrial electrolysis processes for producing nickel and zinc. The challenge is to purify the residue before electrolysis. |
