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.

Stripping chronopotentiometry at scanned deposition potential (SSCP). Part 2. Determination of metal ion speciation parameters
TL;DR: In this article, the DeFord-Hume treatment of polarographic waves is applied to scan deposition potential (SSCP) to measure metal speciation in the sample solution in the presence of simple ligands (i.e. those with non-distributed K and D values).
Journal ArticleDOI
Labile complexes of trace metals in aquatic humic substances: Investigations by means of an ion exchange-based flow procedure
Peter Burba,J. Rocha,D. Klockow +2 more
TL;DR: In this paper, the lability/inertness of heavy metals bound in aquatic humic substances (HS) has been characterized by means of ligand exchange with cellulose-immobilized triethylenetetramine-pentaacetic acid (TETPA) applying a flow system.
Journal ArticleDOI
The interaction of amino acids with the major constituents of natural waters at different ionic strengths
TL;DR: In this article, the interaction of amino acids with the major constituents of natural waters has been studied potentiometrically by determining protonation constants at different ionic strengths (e.g., I ≤ 5.6 mol (kg H 2 O) −1 (NaCl)) and in artificial seawater (containing Na +, K +, Ca 2+, Mg 2+, Cl − and SO 4 2− ) at different salinities.

The aquatic insect Chaoborus as a biomonitor of trace metals in lakes
Landis Hare,André Tessier +1 more
TL;DR: It was found that Cd concentrations in animals were better predicted by free Cd ion concentrations provided that the authors took into account competition between hydrogen ions and free cadmium ions at biological uptake sites, suggesting that this model would provide an effective theoretical framework for the use of Chaoborus larvae as Cd biomonitors in nature.
Journal ArticleDOI
Molecular masses and chromophoric properties of dissolved organic ligands for copper(II) in oceanic water
TL;DR: In this article, the distribution of molecular masses of organic ligands for copper(II) in oceanic water was investigated and the relative contribution of the fraction with low molecular masses ( 10,000 Da fraction) shifted to higher molecular masses, as compared with that of the bulk DOM.
