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.

Journal ArticleDOI
Iron speciation at the riverbank surface in wetland and potential impact on the mobility of trace metals
Gildas Ratié,Delphine Vantelon,E. Lotfi Kalahroodi,Isabelle Bihannic,Anne-Catherine Pierson-Wickmann,Mélanie Davranche +5 more
TL;DR: The results presented here demonstrate that the ferric deposits trap metals on a seasonal basis and are therefore a key factor in the mobilization of metals during riverbank erosion by river flow.
Journal ArticleDOI
The behavior of nickel isotopes at the biogeochemical interface between ultramafic soils and Ni accumulator species
Gildas Ratié,Gildas Ratié,Cécile Quantin,A. Maia de Freitas,Guillaume Echevarria,Emmanuel Ponzevera,Jérémie Garnier +6 more
TL;DR: In this paper, a set of Ni hyperaccumulator and Ni accumulator plants as well as topsoils were sampled on the Barro Alto and Niquelândia ultramafic complexes (Goias State, Brazil).
Journal ArticleDOI
Rotating disk electrode voltammetry/anodic stripping voltammetry for chemical speciation of lead and cadmium in freshwaters containing dissolved organic matter
TL;DR: Rotating disk electrode voltammetry (RDEV) was used to estimate dissociation rate constants and diffusion coefficients, and pseudopolarograms indicated the identity of the metal complexes undergoing electrode reductions at the corresponding plateaus of the pseudopeolarograms in a number of model solutions containing Cd or Pb and known amounts of fulvic acid.

Modelling of the cation binding properties of fulvic acids: an extension of the RANDOM algorithm to include nitrogen and sulphur donor sites
C. D. Woolard,Peter W. Linder +1 more
TL;DR: In this paper, an extension of the original RANDOM algorithm was proposed to all types of fulvic acid including both pedogenic and aquagenic, which is motivated by the authors' interest in modelling metal speciation in seawater.

Formation and stability of mixed Mg2+/Ca2+/phytate species in synthetic seawater media: Consequences on ligand speciation
TL;DR: The results of a potentiometric investigation (by ISE-H+, glass electrode) on the speciation of phytate ion (Phy12−) in an ionic medium simulating the major components (Na+, K+, Ca2+, Mg2+, Cl− and SO42−) of natural seawater, at different salinities and t = 25°C, are reported in this article.
