PROCESS FOR REGENERATING SULFUR DIOXIDE GAS SCRUBBING SOLUTIONS Abstract of the Disclosure It is known to remove sulfur dioxide from gas streams, particularly waste or flue gases, by contact with aqueous scrubbing solutions con- taining a metal salt, such as ferric sulfate, in which the valence of the metal is reduced by the sulfur dioxide. It is also known that such scrubbing solutions can be regenerated by oxi- dizing the reduced metal salt, such as ferrous sulfate, back to the higher valence for further use in removing sulfur dioxide. According to the invention, the regeneration of the scrub- bing solution is advantageously effected by electrolytic or anodic oxidation, rather than air oxidation, of the reduced metal salt, since anodic oxidation is not adversely affected by the increase in sulfuric acid content of the scrubbing solution which results from the con- version of the sulfur dioxide absorbed in the scrubbing solution.
