【Abstract】 A new method, called as the ino-exchange membrane primary cell method, for reduction of Fe 3+ in the titanium sulfate solution has been advanced. The positive compartment of the primary cell consist of lead(copper) electrode and the titanium sulfate solution, and the negative compartment consist of iron electrode and acidic FeSO 4 solution. The anion ion-exchange membrane is used as the diaphragm between two compartments. Fe 3+ in the titanium sulfate solution is reduced by the electric discharge of the primary cell. The effects of temperature, stitrring strength of the solution and membrane area on the reduction rate have been investigated. The experimental result shows that the optimum current density can be higher than 100 A/m 2.更多还原
