Abstract
Removal of sulfur dioxide from an aqueous solution containing the same is effected by subjecting the solution to electrodialytic water splitting. In particular SO.sub.2 is removed from dilute gas streams by means of alkaline solution scrubbing, regeneration of the scrubbing solution and liberation of concentrated SO.sub.2 by means of a membrane water splitter. Waste sulfate produced in the process may be converted to sulfuric acid in a separate membrane water splitter or otherwise processed by conventional means.
