Title:
Adsorption’s Regularities ofRadionuclides on Adsorbents from Solutions |
Abstract:
Uranium isotopes were found in the soil of the locations of numerous thermal andcoldsprings in the Kalbajar region of Azerbaijan in the same proportions as in natural uranium deposits. Uranium isotopes were transferred from soil samples to solutions. Theregularities of adsorption from solutions of uranium isotopes on the surfaces of variousadsorbents are studied. The results of studies of isotope sorption from aqueous solutions on various adsorbents showed high adsorption properties of DOWEX HCR S/Sgranular elastomer, activated carbon and expanded clay. The activation energies ofdesorption of uranium isotopes from the surface of adsorbents were also determined.Relatively low values (22.1-26.3 kJ/mol) of the activation energy of desorptionofuranium isotopes from the surface of adsorbents indicate the absence of the chemical nature of sorption and the presence of only weak van der Waals forces between the absorbed isotopes and the surface of the adsorbents.
