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:

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.
