Description

Novel chromatographic media have been developed for the removal of radionuclides from aqueous waste solutions. Each of these chromatographic materials uses a chemical system designed for highly selective extractions, providing substantial decontamination factors. The removal of transuranics, strontium and uranium from synthetic aqueous wastes or groundwater systems have been considered. For the removal of transuranics, a radial flow column containing TRU · Spec (a supported bifunctional organophosphorus extractant) media was used to concentrate waste solutions containing minimum TRU concentrations of 10-6M. Synthetic waste solutions containing 10-3M 90Sr were concentrated using Sr · Spec (a supported macrocyclic polyether) media. Synthetic groundwater solutions containing 10-4M uranium were concentrated using a supported dialkylphosphinic acid extractant. Potential process scale applications of this technology are described
