New Anion Exchange Resins for Improved Separations of Nuclear Materials

PDF Version Also Available for Download.

Description

We are developing multi-functional anion-exchange resins that facilitate anion uptake by carefully controlling the structure of the anion receptor site. We are attempting to determine if the precepts of ''bite size,'' ''preorganization,'' and ''bidentate'' have an appreciable impact upon electrostatic bonding as they do for covalent bonding. If these precepts do have a positive impact, we will develop new ion-exchange resins that interface the rapidly developing field of ion-specific chelating ligands with robust, commercial ion-exchange technology. The overall objective of our research is to develop a predictive capability that will enable us to design and implement multi-functionalized anion-exchange materials which ... continued below

Description

We are developing multi-functional anion-exchange resins that facilitate anion uptake by carefully controlling the structure of the anion receptor site. We are attempting to determine if the precepts of ''bite size,'' ''preorganization,'' and ''bidentate'' have an appreciable impact upon electrostatic bonding as they do for covalent bonding. If these precepts do have a positive impact, we will develop new ion-exchange resins that interface the rapidly developing field of ion-specific chelating ligands with robust, commercial ion-exchange technology. The overall objective of our research is to develop a predictive capability that will enable us to design and implement multi-functionalized anion-exchange materials which selectively sorb metal complexes of interest from targeted process, waste, and environmental streams. The following Focus Areas and Crosscutting Programs have described needs that would be favorably impacted by the new materials: Efficient Separations and Processing - radionuclide removal (Pu, U, Am) from aqueous phases Plutonium - Pu, Am or total alpha removal to <30 pCi/L before discharge to the environment Plumes - U and Tc in groundwater; U, Pu, Am, and Tc in soils Mixed Waste - radionuclide partitioning High-Level Tank Waste - actinide and Tc removal from supernatants and/or sludges
