A process and method for separating CO.sub.2 from a gaseous stream such as natural gas. An ionic liquid comprising an anion having a carboxylate function and an effective amount of water is used as an adsorbent to selectively complex the CO.sub.2 yielding a gaseous stream with a greatly reduced CO.sub.2 content. The ionic liquid can then be readily be regenerated and recycled.
