ABSTRACT:
Process for separating isotopes of an element. A liquid feed mixture is prepared comprising an aqueous solvent and an ionic surfactant and containing two isotopes of a particular element and an ionizable compound that is present in the mixture. A gas is passed through a pool of the mixture to form bubbles therein, the surface of the bubbles having the surfactant thereon and one isotope of the element preferentially adsorbed thereto as a result of a chemical exchange between the surfactant and another component of the mixture. Thus, the concentration ratio of the isotopes at the bubble surface differs from that in the bulk of the pool. A top fraction is produced at the upper surface of the pool that is enriched in the one isotope as compared to the bulk of the pool. An overhead liquid fraction relatively enriched in the one isotope is collected from the top fraction.
