Concentration / Recovery of H2SO4 using Electrodialysis

Sulphuric acid known as universal solvent is used widely in chemical industry where acidic or anhydrous conditions are required, in its various forms either as dilute or concentrated, as a raw material or a catalyst. The effluent/spent acid generated from industries containing sulphuric acid being hazardous is a major environmental problem that needs to be recovered /separated. Many methods Conventional or Advance have been applied successfully for the recovery of sulphuric acid from waste streams. Membrane separation methods being advantageous and eco-friendly compared to conventional techniques is now being used widely. The present work here focuses on recovery/concentration of laboratory made sample of sulphuric acid using Electrodialysis for different concentration of sulphuric acid solution.
