摘要：The invention relates to the separation, using crown ethers, of uranium andplutonium which are present in an aqueous solution originating from the reprocessing ofirradiated fuels. …This solution (5) is brought into contact at (2) with an organic liquidmembrane (3) containing a crown ether. Uranium and plutonium are extracted into theliquid membrane (3) and then conveyed by this membrane into a receiving solution (7)which becomes enriched in uranium because uranium is conveyed more rapidly thanplutonium. …The crown ether may be DCH 18 C6 or DB 18 C6. ……
