摘要: The metal-finishing and tannery industries have been under strong pressure to replace their current wastewater treatment based on a physicochemical process. electrodialysis process is becoming an interesting alternative for treatment. Electrodialysis membrane separation technique, in which ions are transported from one solution another through ion-exchange membranes, using electric field as the driving force. Blends of polystyrene polyaniline were obtained order produce membranes electrodialysis. produced applied recovery baths industries. parameter evaluation was percentage chromium extraction. results these compared those with commercial Nafion 450.
