Abstract
There is described the selective separation of a gas from a gaseous mixture utilizing a suitable ion-exchange membrane having specific counter-ions electrostatically retained therein, which counter-ions react reversibly with the specific gas molecules to be separated. By this method, the membrane exhibits high selectivity and facilitated transport of the gas across the membrane effecting superior separation of the select gas from the gas mixture.
