Galvanocoagulation (GC) utilizing metallic iron chips and granular coke was studied as a potential technique for decolorization of dye-containing aqueous solutions. GC and chemical coagulation by inorganic metallic coagulants such as iron sulfates (Fe2+, Fe3+) were examined for the removal of individual dyes, used in the fur industry, from model aqueous solutions. The role of metal cations when progressively electrogenerated in situ was compared to when they are added simultaneously. The superio...
