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.

Binding of Cu(II) to algae in a metal buffer
Hanbin Xue,Laura Sigg +1 more
TL;DR: In this paper, the interactions of Cu(II) with algal surfaces and exudates were studied in metal-NTA buffers by a combination of several analytical techniques, and the results were interpreted in terms of conditional equilibrium constants valid at a given pH.
Journal ArticleDOI
Assessment of biosorption mechanism for Pb binding by citrus pectin
Ankit Balaria,Silke Schiewer +1 more
TL;DR: In this article, a study was conducted in order to obtain mechanistic information about Pb binding by low and highly methoxylated citrus pectins, which indicated that carboxylic acid groups are important contributors to negative charge of these biopolymers.
Journal ArticleDOI
Partitioning of trace metals between particulate, colloidal and truly dissolved fractions in a polluted river: the Upper Vistula River (Poland)
Céline Guéguen,Janusz Dominik +1 more
TL;DR: In this paper, the results of trace metal partitioning between particulate (> 1.2 μm), colloidal (1.2μm-1 kDa) and truly dissolved (< 1 kDa), were reported in the polluted section of the Upper Vistula River compared with the non-polluted headwaters.
Journal ArticleDOI
Functions of organic matter in polluted soils: The effect of organic amendments on phytoavailability of heavy metals
TL;DR: In this paper, a conceptual model was developed for soil as a protective barrier against heavy metals uptake by plants and/or migration towards groundwater, and the usefulness of organic matter contained in brown coal, brown coal-derived preparations and farmyard manure was studied as a factor decreasing the uptake of heavy metals by plants.
Journal ArticleDOI
Humic acids: Their detergent qualities and potential uses in pollution remediation
TL;DR: A recently conceived alternative model suggests that humic acids consist of relatively small subunits that associate through weak molecular interactions as mentioned in this paper, which appears to run counter to certain experimental observations, but deserves careful attention.
