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.

A comparative study of polyelectrolyte effects and conformational changes in several purine and pyrimidine homopolyribonucleotides
TL;DR: A comparative study of the acid-base and copper(II) complex-forming properties of homopolyribonugleotides polyuridylic acid, polyinosinic acid and polycytidylic acids has been carried out in this article.
Journal ArticleDOI
Effects of weak organic acids on the size distribution and size-dependent metal binding of humic substances as studied by flow field-flow fractionation
Yuji Yamashita,Takumi Saito +1 more
TL;DR: In this paper, the effects of low molecular weight weak organic acids, which are commonly used as pHbuffering agents, on the hydrodynamic size of purified Aldrich humic acid (PAHA) at pH 7 were investigated by means of flow field flow fractionation.
Journal ArticleDOI
Use of fluorescence spectroscopy and voltammetry for the analysis of metal-organic matter interactions in the New Caledonia lagoon
TL;DR: In this article, fluorescence, polarographic and potentiometric analysis of sea water from the New Caledonia lagoon (located south of Noumea) allowed the determination of the specific properties of the dissolved and particulate phases of organic matter (OM)-metal complexes according to various regions of the lagoon.

The Effect of Hydrodynamic Conditions on the Speciation of Copper at a Chemically Modified Electrode.
Ján Labuda,Mária Vaníačková +1 more
TL;DR: In this paper, the determination of copper in the presence of humic acid and oxalic acid using anodic stripping voltammetry (ASV) at the graphite electrode modified with a copper complexing agents 1-phenyl-3-methyl-4-octanoylpyrazol-5-on, and a Nafion film is described.

Protonation and Complexation Constants of Phosphonic Acids with Cations of Environmental Interest
TL;DR: In this paper, the protonation and complexation constants of two phosphonic acids, namely nitrilotris(methylenephosphonic acid) (AMP) and l-hydroxyethane-1,1′-diphosphonic acids (HEDP) were determined with different cations.
