摘要：
An improvement in the selective removal of SO2 from gases containing SO2 and O2 wherein a thiosulfate-rich aqueous solution containing a sulfite-forming additive is used as the selective SO2 absorbent, whereby a gas of substantially reduced SO2 content and a substantially unchanged O2 content is obtained.
