Adsorption of uranyl onto ferric oxyhydroxides: Application of the surface complexation site-binding model
TLDR
In this paper, the surface complexation-site binding model of Davis et al. was used to predict uranyl adsorption from aqueous electrolyte solution onto well-characterized goethite, amorphous ferric oxyhydroxide and hematite sols at 25°C.About:

Adsorption Parameters for Radioactive Liquid-Waste Migration
TL;DR: In this paper, two levels of pretreatment were applied to the soil to remove carbonate minerals and soluble salts to focus on the remaining mineral fraction, and results are presented from the initial stages of the project.
Study on sorption of radioactive nuclides by carbonates ―present and future researches―
TL;DR: The par-tition coefficient is an important value for the sorption -inclusion process of element into the carbonate crystal and it is calculated empirically and thermodynamically, however, they are quite different as discussed by the authors.

Occurrence of Uranium in Groundwater of Kabirdham, Central India
TL;DR: The groundwater quality with respect to uranium and its seasonal variation in Kabirdham district, Chhattisgarh, India was assessed in this paper, where the uranium content of the collected water samples of the study area varied from <0.5 to 90 µg/L in winter and from < 0.5 µg /L in summer.

Uranium solution-mineral equilibria at low temperatures with applications to sedimentary ore deposits
TL;DR: The Gibbs free energies, enthalpies and entropies of 42 dissolved uranium species and 30 uranium-bearing solid phases have been critically evaluated from the literature and estimated when necessary for 25°C.

Surface ionization and complexation at the oxide/water interface
TL;DR: In this article, a method for determination of intrinsic ionization and complexation constants of oxide surface sites from potentiometric titration data is reported using these experimental properties and the stoichiometry of surface reactions, surface charge, σo, adsorption density, Γi, and diffuse layer potentials, ψd, at the oxide/water interface.

Surface ionization and complexation at the oxide/water interface II. Surface properties of amorphous iron oxyhydroxide and adsorption of metal ions
James A. Davis,James O. Leckie +1 more
TL;DR: In this paper, the site-binding model for the electrical double layer of hydrous oxides reported in a previous paper is applied to the adsorption of metal ions from dilute solution and to complex heterogeneous systems, i.e., amorphous iron oxyhydroxide.
