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.

Antimony interactions with heterogeneous complexants in waters, sediments and soils: A review of binding data for homologous compounds
TL;DR: Antimony binding by NOM and inorganic colloids has been studied in this paper, where it has been shown that antimony adsorption by iron oxides in acidic media takes place via an inner-sphere surface interaction, with the formation of Fe-O-Sb bonds.
Journal ArticleDOI
Polyacrylate Protonation in Various Aqueous Ionic Media at Different Temperatures and Ionic Strengths
TL;DR: In this paper, the protonation constants of polyacrylate anion (molecular mass 2000 Da) were determined in a wide range of ionic strengths in aqueous solution.
Journal ArticleDOI
Antimony interactions with heterogeneous complexants in waters, sediments and soils: A review of data obtained in bulk samples
TL;DR: Antimony association with colloidal and particulate phases is studied in waters, soils and sediments in this article, where various techniques have been used to extract antimony from water, soil and sediment, including simple partition coefficients, size-based speciation methods or sequential extraction techniques.
Journal ArticleDOI
Organo-colloidal control on major- and trace element partitioning in shallow groundwaters : confronting ultrafiltration and modelling
TL;DR: In this paper, two shallow, circumneutral pH waters from the Mercy site wetland (western France) were sampled: one dissolved organic carbon (DOC)- and Fe-rich and a second DOC-rich, and the results showed relatively the same partitioning of these elements as ultrafiltration does.

Scanned stripping chronopotentiometry of metal complexes: lability diagnosis and stability computation
TL;DR: In this article, a method for analyzing the dynamic speciation features of metal complexes based on stripping chronopotentiometry at a scanned deposition potential (SSCP) is presented.
