ABSTRACT:
A method for regenerating a spent bleach-fixer solution by electrodialysis using an electrodialysis cell comprising a cathode, an anode and alternating anion exchange membranes and cation exchange membranes arranged therebetween to define a cathode compartment, a plurality of intermediate enionation and deionation compartments with a set of the deionation compartments alternately disposed between a set of the enionation compartments, and an anode compartment; said method comprising filling an electrolyte solution in the cathode compartment, the enionation compartments and anode compartment, and the spent bleach-fixer solution in the deionation compartments, and passing a direct electric current across the cathode and the anode; and an apparatus for use in the aforesaid method.
