摘要
Chlorine is selectively cathodically electrolytically removed from aqueous solutions of chlorine dioxide and chlorine by the application of an electrode potential at a pH of the aqueous solution of up to about 4. Chlorine is electrolytically reduced to chloride ions while the concentration of the chlorine dioxide remains substantially the same in the treated solution. The chlorine reduction is effected directly at pH values up to about 2 usin g a low overpotential cathode and indirectly at pH values up to about 4 using a high overpotential cathode.
