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 of Neptunium(V) on Hydrargilite
TL;DR: In this paper, the sorption of tracer concentrations of neptunium(V) on hydrargilite was studied both under C02-free conditions and with aqueous solutions with a low total concentration of carbonate (CIO 4 mol · L ').

Adsorption of Fe(III), Co(II) and Zn(II) onto particulates in fresh waters on the basis of the surface complexation model I. Stabilities of metal species adsorbed on particulates
TL;DR: In this paper, the concentrations of iron, manganese, cobalt and zinc in water were determined and compared with those predicted on the basis of the surface complexation model.

Radiation-induced defects in kaolinites: indirect assessment of radionuclide migration in the geosphere
TL;DR: In this article, the irradiation origin of these paramagnetic defect centres (PDC) is demonstrated by artificial irradiation (four types have been used: X-ray, γ-rays, He+ and Pb2+ ion beam implantation) of kaolinites representing different formation conditions (hydrothermal, weathering, synthesis).

Remediation of groundwater
TL;DR: In this paper, a groundwater remediation method for treating acidic or alkaline groundwater containing divalent and trivalent metal cations is proposed, which includes the step of injecting a slurry or suspension of solid alkaline material into the ground, the slurry being injected into one or more regions such that the groundwater contacts the solid alkalinaline material and the divalent/trivalent metals react to form a layered double hydroxide (LDH) material.

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.
