This invention describes a technology that can capture radioactive contaminants from wastewater. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
Radioactive isotopes in liquid nuclear wastes are difficult to remove through conventional methods. Solvent extraction and ion exchange have proved successful for removal, but most of these materials display low selectivity and require the use of environmentally unsafe solvents.
NETL researchers have developed low-cost, scalable and robust amine-based sorbents that have been shown to effectively remove radioactive isotopes from liquids. These materials show promise for commercial-scale processes involving radioactive ions capture from flowing aqueous streams or stagnant aqueous environments.
Theses novel sorbents exhibit major advantages over existing methods.
