Determination of metal ion binding parameters for humic substances ☆: Part 2. Utility of ASV pseudo-polarography
TL;DR: In this article, a pseudo-polarographic approach was applied to the extraction of metal ion binding parameters from reverse pulse polarograms for fulvic substances, which allowed measurements to be made at low (environmentally relevant) concentrations and overcomes problems associated with processes occurring during stripping step.
Journal ArticleDOI
Equilibrium dialysis-ligand exchange: adaptation of the method for determination of conditional stability constants of radionuclide-fulvic acid complexes
TL;DR: In this paper, the conditional stability constants (cKFA) of Laurentian Soil fulvic acid are determined at various pH values and ionic strengths for the binding of Co2+ and UO2+2.

Copper(II) Complexation Properties and Surfactant Activity of 3-[N,N-Bis(2-hydroxyethyl)amino]-2-hydroxypropanesulfonic Acid andN-(2-Hydroxyethyl)piperazine-N′-2-hydroxypropanesulfonic Acid pH Buffers Which May Affect Trace Metal Speciation inin VitroStudies
TL;DR: The copper-complexing capacity and the surfactant activity of three compounds, 3-[N,N-bis (2-hydroxyethyl)amino]-2-Hydroxypropanesulfonic acid (DIPSO), HEPPSO, and piperazine-n,N'-bis(2-ethanesulfonic Acid (Pipes) were investigated, confirming no copper(II) complexation by Pipes.

Determination of metal ions concentration and speciation in seawater by titration with an iminodiacetic resin
TL;DR: In this article, a chelating resin containing iminodiacetic groups, Chelex 100 which is often employed for sorbing metal ions from complex matrices, was used for separating and preconcentrating heavy metal ion from seawater samples.
Journal ArticleDOI
On lability of chemically heterogeneous systems : complexes between trace metals and humic matter
TL;DR: In this paper, the lability of cadmium and lead complexes in different samples of fulvic and humic matter (chemically heterogeneous systems) was investigated on a more rigorous level and explained how lability varies with the stability of the chemically heterogeneous complex.

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.

TL;DR: The Dynamic Green Ocean Model (DGOM) as mentioned in this paper is based on the identification of key plankton functional types that need to be simulated explicitly to capture important biogeochemical processes in the ocean, and sources of information necessary to parameterize each of these processes within a modeling framework.
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.

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.
