Metal flux and dynamic speciation at (bio)interfaces. Part III: MHEDYN, a general code for metal flux computation; application to simple and fulvic complexants.
TL;DR: These papers describe the dynamic contribution of the various types of sites for fulvic and aggregate Cu(II) complexes for the first time.

Competitive ligand exchange/adsorptive cathodic stripping voltammetry (CLE/AdCSV) for kinetic studies of nickel speciation in aqueous environmental samples containing heterogeneous, macromolecular, organic complexants
TL;DR: In this paper, the competitive ligand exchange/adsorptive cathodic stripping voltammetry (CLE/AdCSV) was applied to the kinetic speciation of nickel in aqueous environmental samples containing heterogeneous, macromolecular, organic complexants.
Journal ArticleDOI
Comparison of microgels, extracellular polymeric substances (EPS) and transparent exopolymeric particles (TEP) determined in seawater with and without oil
Chen Xu,Wei-Chun Chin,Peng Lin,Hongmei Chen,Meng-Hsuen Chiu,Derek C. Waggoner,Wei Xing,Luni Sun,Kathleen A. Schwehr,Patrick G. Hatcher,Antonietta Quigg,Peter H. Santschi +11 more
TL;DR: In this article, the authors compared the concentrations of the three terms in a water-accommodated fraction (WAF) of oil and seawater (control) in the same sample.
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.

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.

Watson,Dieter Wolf-Gladrow +23 more
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.
