Application of a chelite P modified carbon paste electrode to copper analysis and speciation
TL;DR: In this paper, a carbon paste electrode modified with the commercial resin Chelite P, containing amino-phosphonic groups, was used in the determination and speciation of copper in the Jarama river in Madrid.
Journal ArticleDOI
Voltammetric study of cadmium(II) ion in the presence of polysaccharides
TL;DR: The complex formation of Cd(II) with alginic and polygalacturonic acids is studied by normal pulse (NPP), reverse pulse (RPP), and differential pulse polarography (DPP) as discussed by the authors.
Journal ArticleDOI
Analysis of metals and EOX in sludge from municipal wastewater treatment plants: A case study
TL;DR: The lowest concentrations of EOX were found in sludge coming from the smallest MWWTPs, which is to be considered more suitable for agricultural use, and analytical assays on composts, peat and soils were performed to compare EOX concentrations between these matrices and sludge.
Journal ArticleDOI
Combination of 13C/113Cd NMR, potentiometry, and voltammetry in characterizing the interactions between Cd and two models of the main components of soil organic matter
TL;DR: The binding parameters obtained by fitting can be used in biogeochemical models to better define the role of key SOM compounds like exudates of roots and of soil bacteria on trace metal transport or assimilation.

Influence of trivalent electrolytes on the humic colloid-borne transport of contaminant metals: competition and flocculation effects
H. Lippold,A. Mansel,H. Kupsch +2 more
TL;DR: It can be inferred that the possibility of significant competitive effects in natural aquatic systems is confined to Al(III), and Precipitation is attributed to homocoagulation of humic colloids induced by charge compensation, which is further supported by flocculation experiments with Al( III) depending on pH, ionic strength, and humic acid concentration.

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.
Journal ArticleDOI
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.
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.
