Journal ArticleDOI
Heterogeneity of natural organic matter from the Chena River, Alaska.
TL;DR: Results of py-GC/MS showed that the percentage of polysaccharides decreased with decreasing size, further supporting a degradation pathway of NOM from POM to COM and DOM in Chena River waters.
Journal ArticleDOI
Characterization of different humic materials by various analytical techniques
TL;DR: In this article, the same humic fractions were investigated by the developed analytical methods CP/MAS 13 C NMR, IR and visible spectroscopy's; to evaluate the harmony of the different analytical methods used for characterization of humic materials and to recognize and evaluate the properties of Humic acid, fulvic acid and humin separated from the same source.
Journal ArticleDOI
Metal speciation dynamics and bioavailability: Zn(II) and Cd(II) uptake by mussel (Mytilus edulis) and carp (Cyprinus carpio).
TL;DR: Coupling of the ensuing diffusional mass transfer flux of metal with the biouptake flux of free metal, the supposedly bioactive species, shows under which conditions labile metal complexes can contribute to the uptake.
Journal ArticleDOI
Effect of Pseudokirchneriella subcapitata (Chlorophyceae) exudates on metal toxicity and colloid aggregation.
Brahim Koukal,Patrick Rossé,Alain Reinhardt,Benoît J.D. Ferrari,Kevin J. Wilkinson,Jean-Luc Loizeau,Janusz Dominik +6 more
TL;DR: Algal exudates play an important role in the biogeochemical cycling of metals in natural surface water: by reducing free metal concentrations and toxicity to living organisms and by favoring colloid aggregation leading to the removal of colloid-bound metals (colloidal pumping).
Journal ArticleDOI
Applications of electrochemical data analysis by multivariate curve resolution-alternating least squares
TL;DR: In this paper, a comprehensive review on different applications of multivariate curve resolution-alternating least squares (MCR-ALS) in electrochemistry is presented, such as complexation studies, small molecule-biomacromolecule interactions, minimization of electrodic adsorption, separation of the faradic current contribution from total current to enhance the sensitivity of the electroanalytical techniques, quantification and spectroelectrochemistry.

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.
