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.

Spatio-temporal variation in the characteristics of dissolved organic matter in the streams of boreal forests: impacts on modelled copper speciation
TL;DR: It is concluded that some source-based differences in DOM that may result from variation in both catchment characteristics and seasonal DOC loadings necessitate the determination of location-specific and/or seasonal site density values due to the resulting variability in metal speciation that has been predicted through modelling.
Journal ArticleDOI
Mathematical Description of Metal Retention with Water-Soluble Polymers during Membrane Filtration
TL;DR: In this paper, a theoretical approach to describe metal retention and enrichment in aqueous solution by soluble polymeric reagents during membrane filtration is proposed, using mathematical models based on the theory of kinetics of reactions in partially open systems.
Journal ArticleDOI
Dissolved organic-matter, cadmium, copper and zinc in pig slurry-size and soil solution-size exclusion chromatography fractions
TL;DR: In this paper, the authors used separation size exclusion chromatography (SSEC) to prepare molecular size fractions from liquid pig slurry, before and after aerobic interaction with a loamy-sand soil.
Journal ArticleDOI
Laser-induced fluorescence of marine sedimentary interstitial dissolved organic matter
TL;DR: In this article, a self-made experimental laser-crystal fluorimeter and two classical spectrofluorimeters are employed (Perkin Elmer LS-2 and LS-50).

Valorisation of marine Pelvetia canaliculata Ochrophyta for separation and recovery of nickel from water: Equilibrium and kinetics modeling on Na-loaded algae
TL;DR: In this paper, the authors studied the biosorption of Ni2+ by Na-loaded (raw algae treated with NaCl), algae Pelvetia canaliculata Ochrophyta, was studied in a batch system.
