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.

Multivariate curve resolution analysis of voltammetric data obtained at different time windows: study of the system Cd2+–nitrilotriacetic acid
Marta Torres,José Manuel Díaz-Cruz,Cristina Ariño,Bozidar S Grabaric,Romà Tauler,Miquel Esteban +5 more
TL;DR: In this paper, the system Cd2+−nitrilotriacetic acid (NTA) has been studied by voltammetric techniques with different time windows (long drop time direct current polarography, differential pulse polarography and differential pulse anodic stripping voltammetry), in a way that, depending on the technique, the 1:1 complex behaves mainly labile or mainly inert.

Metal Speciation: Concepts, Analysis and Effects
Laura Sigg,Hanbin Xue +1 more
TL;DR: In this paper, the free aquo metal ion concentration, that is a key parameter for the effects of metals, is regulated by the complex interactions between trace metal ions, ligands and major ions.
Journal ArticleDOI
Understanding what we are measuring: standards and quantification of natural organic matter.
TL;DR: The case of natural organic matter types is discussed here for four different categories: carbohydrates, thiols, TEP (transparent exopolymers), and humic substances in freshwaters, where the results obtained are noticeably dependent on the standard, though the type of dependency varies.

Spatial and temporal heavy metal concentration (Cu, Pb, Zn, Hg, Fe, Mn, Hg) in sediments of the Mar Piccolo in Taranto (Ionian Sea, Italy)
Bianca Maria Petronio,Nicola Cardellicchio,Nicoletta Calace,Marco Pietroletti,Massimiliana Pietrantonio,Lucia Caliandro +5 more
TL;DR: In this paper, the authors analyzed three sediment cores collected on the basis of the pollution sources and showed that heavy metal and organic carbon concentrations underline the fact that anthropogenic input is different in the three sites, and that in time the amount of pollutants coming into the Mar Piccolo have changed in different ways.

TL;DR: The new differential pulse cathodic stripping voltammetry was successfully applied to measure glutathione- like compounds (GSHs), thioacetamide-like compounds (TAs) and the liquid chromatography coupled to organic detector to analyze HS and DOC at high frequency in the Penzé River (NW France).
