ABSTRACT:
Sulfur dioxide is removed from a fluid containing SO.sub.2 by employing as an absorbent therefor an aqueous solution of compound represented by Formula I: ##STR1## wherein X is --O--, --NR.sup.1 --, or --N.dbd.; each Y is independently --(CR.sup.2.sub.2)--, --(C.dbd.O)--, --O--, --NR.sup.1 --, --N.dbd., or --C(R.sup.2).dbd.; each R.sup.1 or R.sup.2 is independently hydrogen; an alkyl group; a hydroxyalkyl group; an aldehyde group; a carboxylic acid or salt group; or an alkyl group containing an aldehyde group, a carboxylic acid or salt group, ketone, carboxylic ester, ether, or sulfoxide group; and m is an integer preferably of from 2 to about 4. The absorbent solution preferably can be thermally regenerated by heating to remove SO.sub.2.
