Adsorption of heavy metal ions on soils and soils constituents
TL;DR: Empirical and mechanistic model approaches for heavy metal adsorption and parameter determination in such models have been reviewed and Sorption mechanisms in soils, the influence of surface functional groups and surface complexation as well as parameters influencing adsorbption are discussed.
Journal ArticleDOI
Colloid mobilization and transport in groundwater
TL;DR: In this paper, the authors present theories describing colloid mobilization, deposition, and transport, laboratory experiments in model systems designed to test these theories, and applications of these theories to colloid-facilitated transport experiments in natural groundwater systems.
Journal ArticleDOI
Arsenate and Chromate Retention Mechanisms on Goethite. 1. Surface Structure
TL;DR: In this paper, the authors used Extended X-ray absorption fine structure (EXAFS) spectroscopy to deduce the local coordination environment of two environmental contaminants, arsenate and chromate, on the mineral goethite (α-FeOOH).

The charge of glass and silica surfaces
TL;DR: In this paper, the authors present a method of calculating the electric charge density of glass and silica surfaces in contact with aqueous electrolytes for two cases of practical relevance that are not amenable to standard techniques: surfaces of low specific area at low ionic strength and surfaces interacting strongly with another anionic surface.

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.

Adsorption of uranyl onto ferric oxyhydroxides: Application of the surface complexation site-binding model
TL;DR: 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.
Journal ArticleDOI
Anion adsorption by goethite and gibbsite
TL;DR: The relationship between adsorption and pH varies with the pKa, of the conjugate acid of the anion, for several adsorbents in presence of an excess of specifically adsorbed anions.

TL;DR: In this article, a surface complexation model is used to describe the dependence of the extent of adsorption on pH and other solution variables, and a set of equilibrium constants has been determined which permits calculation of the amount bound to the surface and of the surface charge as a function of pH and total concentrations.
