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
Steady-state DGT fluxes of nanoparticulate metal complexes
TL;DR: For a fully labile complex system, the diffusive gradients in thin film (DGT) metal flux approaches the fairly simple limit defined by the joint diffusion of the free metal ion and the complex species in the gel layer Natural soft nanoparticulate complexes such as those with humics and fulvics, generally enter the DGT gel phase and some of them may even be adsorbed by the gel matrix as discussed by the authors.
Journal ArticleDOI
Seasonal variation in the composition of aquatic organic matter in some Nova Scotian brownwaters: a nuclear magnetic resonance approach
TL;DR: Using a novel concentration technique (reverse osmosis and freeze-drying) as well as a standard analytical technique little used with limnological samples (solid state 13C nuclear magnetic resonance), the authors studied the chemical structure of aquatic organic matter from four closely located freshwater sites in Nova Scotia.
Journal ArticleDOI
Quantifying 'humics' in freshwaters: purpose and methods
TL;DR: In this article, a review of the existing methods for humic substance quantification is presented, and the implications of the current lack of simple measurement methods are discussed in relation to two fields of high environmental relevance: trace element speciation modelling and natural colloid and engineered nanoparticle fate.
Caracterização de lodo gerado em estações de tratamento de água: perspectivas de aplicação agrícola
TL;DR: In this article, the characterization of sludges produced at water treatment plants in Jaboticabal-SP using FeCl3 as flocculant, and in Taquaritinga-SP and Manaus-AM using Al2(SO4)3 as a flocculusant.

Anodic stripping voltammetry in the complexation study of the peptide Lys-Cys-Thr-Cys-Cys-Ala [56–61] MT I and cadmium: application in determination of the complexing capacity and stability constant
Marijana Erk,Biserka Raspor +1 more
TL;DR: In this article, the capacity of FT to complex Cd (C L ) and the apparent stability constant of the CdFT complex ( K ) using a modified van den Berg-Ružic-Lee method were determined.
