Electrochemical metal speciation analysis of chemically heterogeneous samples: the outstanding features of stripping chronopotentiometry at scanned deposition potential
TL;DR: The application of depletive stripping chronopotentiometry at scanned deposition potential (SSCP) to metal ion speciation analysis of chemically heterogeneous complex systems is described and the effect of heterogeneity, as manifested in flattening of the SSCP wave, can be distinguished from that of electrochemical irreversibility.
Journal ArticleDOI
Permeation liquid membrane as a tool for monitoring bioavailable Pb in natural waters
TL;DR: In this paper, a planar sheet permeation liquid membrane (PLM) has been characterized by measuring Pb fluxes in the absence and presence of tiron and nitrilotriacetic, iminodiacetic, malonic, citric, polyacrylic and fulvic (Suwannee River fulvic, SRFA) acids.
Journal ArticleDOI
In vivo effects of copper on the calcium homeostasis mechanisms of mussel gill cell plasma membranes
TL;DR: Recovery of enzyme functionality and glutathione levels, notwithstanding progressive Cu2+ accumulation in mussel gill tissue, suggests the activation of metal-induced cell detoxification systems.
Journal ArticleDOI
Distribution of phosphorus in particulate, colloidal and molecular-sized fractions of soil solution.
TL;DR: In this paper, the total P in soil solution can be divided into three procedurally defined components namely molybdate reactive P (MRP), organic P (OP) and condensed P (CP).
Journal ArticleDOI
Colloid properties in granitic groundwater systems. II : Stability and transport study
TL;DR: In this paper, the authors used Montmorillonite colloids as a model material because colloids in granitic groundwaters comprise phyllosilicates (Part I) and found that the small colloid concentration in a representative deep crystalline water (100 nm) is a consequence of an attachment factor for clay colloids (e.g. montmorillonites) close to 1, and limits the colloids transport.

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.
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.
