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
Humic acids coagulation: influence of divalent cations
TL;DR: In this article, the effects of ionic strength (maintained by LiCl, NaCl or KCl) and Ca2+ and Mg2+ concentration on the coagulation of purified humic acids (HA) was studied.
Journal ArticleDOI
Chemical weathering in a tropical watershed, Luquillo Mountains, Puerto Rico III: quartz dissolution rates
Marjorie S. Schulz,Art F. White +1 more
TL;DR: The paucity of weathering rates for quartz in the natural environment stems both from the slow rate at which quartz dissolves and the difficulty in differentiating solute Si contributed by quartz from that derived from other silicate minerals as mentioned in this paper.
Journal ArticleDOI
Re-examination of cross-flow ultrafiltration for sampling aquatic colloids: evidence from molecular probes
TL;DR: In this article, the retention and permeation behavior of macromolecules and their associated trace elements during ultra-filtration is still controversial, and the possibility for a ''breakthrough'' of high molecular weight HMW dissolved organic carbon DOC during ultrafiltration are still a matter of contention.
Journal ArticleDOI
Reactivity of Freshly Formed Fe(III) in Synthetic Solutions and (Pore)Waters: Voltammetric Evidence of an Aging Process
TL;DR: In this paper, a laboratory and field study showed that soluble Fe(III) complexed to organic ligands exists in sediment porewaters, suggesting that aggregation occurs in solution, and a mathematical model was successfully developed to assess a mechanism for this aging process.
Journal ArticleDOI
Environmental geochemistry at the global scale
TL;DR: In this article, the International Union of Geological Surveys (IUGS) and the International Association of Geochemistry and Cosmochemistry (IAGC) have made preparations for the establishment of a global database for monitoring the state of the environment and identifying problem areas.
