Abstract

PURPOSE: To regenerate a used photographic fixer as well as recover silver by electrolyzing the fixer contg. silver besides thiosulfuric acid ions as a principal component using a cation exchange membrane as a diaphragm.
CONSTITUTION: Anode chamber 2 provided with anode 4 and cathode chamber 1 provided with cathode 5 are separated by cation exchange membrane 3. Chamber 2 is filled with a buffer soln. of ≥about 5pH or an alkali soln. of about 10pH, and chamber 1 with a used photographic fixer contg. silver basides thiosulfuric acid ions as a principal component. The fixer is then electrolyzed. By this method the silver is recovered from cathode 5, and since the ions in the fixer are perfectly confined in chamber 1, they are not electrolyzed. Simultaneously, the silver-free solu. is recovered as the fixer.
