ABSTRACT:
A process for electrolyzing a bleach-fixed solution, or blix solution, used in processing color photographic materials, which contains originally an iron (III) chelate compound and a silver halide solvent in an electrolytic bath and separating the cathode compartment and the anode compartment of the electrolytic cell with a porous membrane and controlling the anode potential so that the silver halide solvent does not decompose. Embodiments include use of a carbon fiber as the anode and also controlling the cathode potential and the current densities of the cathode and the anode.
