FIELD: chemistry.
SUBSTANCE: invention relates to a method for producing elemental sulfur. In the method, an aqueous solution containing bisulfite interacts with oxidized sulfide-oxidizing bacteria under anaerobic conditions, in which elemental sulfur and reduced sulfide-oxidizing bacteria are obtained. Then, reduced sulfide-oxidizing bacteria are oxidized by transferring electrons to an anode of an electrochemical cell to produce oxidized sulfide-oxidizing bacteria.
EFFECT: formation of thiosulfates is reduced.
