ABSTRACT:
An aqueous solution comprising one or more sulfur-containing anions is introduced into a diaphragmless, mercury, electrolytic cell wherein, in the presence of an impressed direct electric current, the sulfur-containing anions are electro-chemically converted to elemental sulfur. The invention will be found most advantageous in treating spent aqueous absorbents recovered from processes for removing SO.sub.2 and SO.sub.3 from stack gases.
