Title: Novel extraction chromatographic materials for the separation and preconcentration of radionuclides

Abstract

New chromatographic methods have been developed to separate and preconcentrate the actinide elements and radiostrontium from a variety of biological and environmental samples. Several of these methods involve the use, in an extraction chromatographic mode, of a chemical system originally devised for the removal of various radionuclides from acidic, high-level nuclear waste solutions. For the isolation of actinides, for example, a solution of the sample in nitric acid is passed through a column containing a solution of CMPO in tributyl phosphate (the basis of the well-known TRUEX process) sorbed on an inert polymeric substrate. Isolation of radiostrontium is accomplished by passing a sample solution, again in nitric acid, through a column containing a polymeric support impregnated with an octanol solution of di-t-butylcyclohexano-18-crown-6 (the basis of the SREX process for strontium removal from nuclear wastes). Sorbed strontium can be eluted with dilute nitric acid and counted via liquid scintillation. A variety of applications of these and other related materials to the analysis of environmental and biological samples are described.
