摘要： A method for the separation of carbon dioxide from a gas mixture is described in which a dendrimer selective for carbon dioxide is present in an immobilized liquid membrane, the dendrimer being either in pure form or optionally with at least one solvent, such as but not limited to glycerol, polyethylene glycol, water, refrigerated methanol, NMP, or glycerol carbonate, the latter also having selective carbon dioxide properties as will be described below. In another embodiment, a dendrimer selective for carbon dioxide and capable of forming a film may be used in the method as the membrane itself, optionally with at least one solvent.
