ABSTRACT:
A process for removing SO.sub.2 from a fluid containing SO.sub.2 by employing as an absorbent for the SO.sub.2 an admixture of water and a compound represented by Formula I: ##STR1## wherein each R.sup.1, R.sup.2 or R.sup.3 is independently hydrogen; an alkyl group; a carboxylic acid group; a hydroxyalkyl group; an aldehyde group; and alkyl group containing a carboxylic ester, a carboxylic acid or salt, ether, aldehyde, ketone or sulfoxide group; wherein at least one R.sup.1 or R.sup.3 is carboxy methyl group and at least one R.sup.1 or R.sup.3 is hydrogen, preferably at least one R.sup.1 is carboxy methyl and at least one R.sup.3 is hydrogen. The absorbent solution preferably can be thermally regenerated by heating to remove SO.sub.2.
