Speciation of Cadmium in the Environment
TL;DR: This chapter reports an analysis of literature dedicated to the speciation of cadmium in various environmental compartments, i.e., atmosphere, natural waters, soils and sediments, as well as modelling its reactivity towards the main classes of ligands usually present in natural systems.
Journal ArticleDOI
Ultrafiltration and determination of Zn- and Cu-humic substances complexes stability constants
TL;DR: In this paper, the size fractionation of humic substances (HS) and their metal complexes by ultrafiltration is an efficient procedure for simultaneous determination of stability constants using sequential-stage ultra-filtration and a radiotracer technique.
Journal ArticleDOI
Lability of heavy metal species in aquatic humic substances characterized by ion exchange with cellulose phosphate.
TL;DR: Labile metal species in aquatic humic substances (HSs) were characterized by ion exchange on cellulose phosphate (CellPhos) by applying an optimized batch procedure and the required metal determinations were carried out by atomic absorption spectrometry.
Journal ArticleDOI
NOM site binding heterogeneity in natural waters: Discrete approaches
TL;DR: In this article, the authors discuss how one of the main features of NOM, the heterogeneity of their binding sites, is taken into account in existing discrete models, and a better understanding of this aspect should help the potential user to decide which strategy could be used to solve a particular problem.
Journal ArticleDOI
Functional speciation of metal-dissolved organic matter complexes by size exclusion chromatography coupled to inductively coupled plasma mass spectrometry and deconvolution analysis
TL;DR: In this paper, a functional speciation approach based on the determination of the metals associated to different groups of homologous compounds has been followed to the characterization of metal-dissolved organic matter complexes in compost leachates.

Journal ArticleDOI
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

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.
