- Abstract
Dynamics of Pu and Am distribution between components of the system soil-water-carboxylic resin is studied for soils with various absorbing (clay-humus) complexes. The fractional composition of organic components of the aqueous phase of the system and TUE content in the fractions were examined to elucidate the Pu and Am speciation in the solution. The Pu and Am concentrations in the aqueous phase strongly depend on the content and composition of the soil humus matter. Transuranic elements are associated essentially with the humic acid fractions, this trend being more pronounced for Pu. In the system with increased humus content, TUE occur in the solution as complexes with humus substances, and in the system with lower humus content, as hydrolyzed species. The features of sorption processes occurring on the clay- humus complex of the soil were judged from the sorption isotherms of the radionuclides on a resin. Sorption on the resin is controlled by the Pu and Am speciation in the solution.
