Abstract
A novel extraction chromatographic resin comprised of a quaternary ami ne-based liquid anion exchanger sorbed on an inert polymeric substrate for the sorption of actinides from nitric and hydrochloric acids is d escribed. The resin is shown to exhibit preferential retention of tetr avalent actinides over a wide range of acidities. The application of t his material to the separation and preconcentration of selected actini des from high level nuclear waste solutions for subsequent determinati on is described.
