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.

Development of a simple extraction procedure using ligand competition for biogeochemically available metals of estuarine suspended particulate matter
David J Whitworth,Eric P. Achterberg,Véronique Herzl,Malcolm Nimmo,Martha Gledhill,Paul J. Worsfold +5 more
TL;DR: In this paper, a single extraction procedure for SPM-associated trace metals, using a ligand competition approach with EDTA as the added complexing ligand, was described, and the equilibrium times between EDTA and particulate material of 72h were required to reach equilibrium for most of the metals studied.
Journal ArticleDOI
Copper (II) complexation in northern California rice field waters: an investigation using differential pulse anodic and cathodic stripping voltammetry
TL;DR: It is demonstrated that > or = 99% of the dissolved copper in five rice field waters, one river water and a catchment basin water collected at sites in northern California is complexed by natural organic matter.
Journal ArticleDOI
Fluorescence quenching of three molecular weight fractions of a soil fulvic acid by UO2(II)
TL;DR: A soil fulvic acid isolated from a Korean forest was divided into three different molecular weight fractions by gel filtration chromatography and the fractions were studied by synchronous fluorescence (SyF) spectroscopy, which indicated a stronger affinity for UO(2)(II) in the fraction with molecules of larger size.

Distribution of organic carbon, selected stable elements and artificial radionuclides among dissolved, colloidal and particulate phases in the Rhône River (France): Preliminary results
F. Eyrolle,Sabine Charmasson +1 more
TL;DR: The behaviour of radionuclides discharged from nuclear facilities in the Rhône River depends on their distribution among the dissolved, colloidal and particulate phases, and it is shown that organic colloids account for 11% of the total organic carbon content.

Cadmium complexation with bisulfide
Feiyue Wang,André Tessier +1 more
TL;DR: In this paper, the authors used in situ dialysis to measure the solubility of CdS(s) in sulfidic solutions, and they showed that these three solids at various pH values (4.2−8.6) and sulfide concentrations (10-4.3−10-1.3 M) can be reproduced adequately by the following four bisulfide complexes: CdHS+, Cd(HS)2, Cd (HS)3-, and Cd
