ABSTRACT:
A process for the preferential absorption of H.sub.2 S from a gas which contains H.sub.2 S and CO.sub.2 comprises contacting of the gas with a sorbent solution comprising alkali metal ethylenediaminetetraacetate and/or alkali metal nitrilotriacetate, in the substantial absence of oxidizing agents which can oxidize H.sub.2 S.
