WHAM—a chemical equilibrium model and computer code for waters, sediments, and soils incorporating a discrete site/electrostatic model of ion-binding by humic substances
TL;DR: The WHAM (Windermere Humic Aqueous Model) as mentioned in this paper is a simple inorganic speciation code for aqueous solutions that combines Humic Ion-Binding Model V with a simple, inorganic inorganic specciation code.

Ion binding to natural organic matter : competition, heterogeneity, stoichiometry and thermodynamic consistency
David G. Kinniburgh,Willem H. van Riemsdijk,Luuk K. Koopal,Michal Borkovec,Marc F. Benedetti,Marcelo Javier Avena +5 more
TL;DR: The NICCA-Donnan model as mentioned in this paper is a semi-empirical model that is similar to the NICA-donnan model except that it introduces an additional degree of scaling that ensures thermodynamic consistency and allows for variable stoichiometry of binding, which implicitly accounts for the large degree of chemical heterogeneity of humic particles.
Journal ArticleDOI
A unifying model of cation binding by humic substances
TL;DR: Model V describes the binding of ions by humic substances in terms of complexation at discrete sites, modified by electrostatic attraction and/or repulsion, and also takes account of nonspecific binding due to counterion accumulation.
Journal ArticleDOI
A Generalized Description of Aquatic Colloidal Interactions: The Three-colloidal Component Approach
TL;DR: In this article, the physicochemical properties of the different groups of colloids are described, and the role of each colloid class is discussed with respect to homoaggregation (aggregation within a given colloid) and hetero-aggregation among different colloid types.
Journal ArticleDOI
The effect of humic acid adsorption on pH-dependent surface charging and aggregation of magnetite nanoparticles
Erzsébet Illés,Etelka Tombácz +1 more
TL;DR: The pH-dependent adsorption of humic acid (HA) on magnetite and its effect on the surface charging and the aggregation of oxide particles were investigated and nanoparticles are stabilized in a way of combined steric and electrostatic effects.

TL;DR: In this paper, rank annihilation factor analysis (RAFA) and evolutionary factor analysis were applied to resolve the two-way equilibrium spectrophotometric data for the determination of stability constants of the complexes of 1,8-bis(o-aminophenoxy)-3,6-dioxaoctane (BOAPD) with Co 2+, Ni 2+, Cu 2+, Zn 2+, Cd 2+, and Pb 2+ ions.

Catherine A. Murimboh,Jianfu Deng,John Murimboh,John Murimboh,Jeffrey Guthrie,Chuni L. Chakrabarti,David R. S. Lean +6 more
TL;DR: In this article, an improved theoretical approach to Anodic Stripping Voltammetry with a Thin Mercury Film Rotating Disk Electrode for elucidating the nature of the interactions of Pb(II, Cd(II), Zn(II) with humic substances was presented.
Book ChapterDOI
The incorporation of natural organic matter — cation interaction into the speciation code PHREEQE
TL;DR: In this article, a more realistic approach has been incorporated into the speciation code PHREEQE using an electrostatic (surface complexation) model assuming the organic molecules form rigid, impenetrable spheres.

Influence of Acidity and Uranyl Nitrate Concentration on the Efficiency of Recovery of Uranium(VI) from Aqueous Solutions with Hydrolytic Wood Lignin
TL;DR: In this paper, the efficiency of recovery of uranium(VI) from aqueous solutions with hydrolytic lignin and strength of binding of uranium to Lignin were studied in relation to the uranium concentration and acidity.
