Abstract
UTEVA and TRU extraction chromatographic resins, the products of Eichrom Technologies Inc. have been systematically studied with the objective to develop a procedure for the simultaneous determination of Th, U, Np, Pu and Am nuclides. Elution chromatograms of the spiked model solutions and environmental samples were determined under different conditions (in nitric and hydrochloric acids, in oxidative and reducing media) using inductively coupled plasma mass spectrometry (ICP-MS). Resin capacity factors (k′) for the actinides in different oxidation states were obtained and the interaction of the analytes with each other and the resin matrices were revealed. Data obtained contribute to the better understanding of the mechanism of the extraction chromatography of the actinides and provide additional information about the properties of UTEVA and TRU described by Horwitz et al.
