Influence of N-Substituted Aminosulfonic Acids with a Morpholinic Ring pH Buffers on the Redox Processes of Copper or Zinc Ions: A Contribution to Speciation Studies
TL;DR: In this article, the electrochemical behavior of copper or zinc metal ions was investigated in the presence of different pH buffers [3-(Nmorpholino)-2-hydroxypropanesulfonic acid (MOPSO), 2-(N-morpholinos)ethane sulfonic acid(MES), and 3-(n-morpholine), polyphenolic acid (POPSO) by differential pulse anodic stripping voltammetry (DPASV) and differential pulse polarography (DPP).

Highly Organic Soils as “Witnesses” of Anthropogenic Pb, Cu, Zn, and 137Cs Inputs During Centuries
TL;DR: In this paper, an undisturbed peat profile was cored in 2005 from a Swiss ombrotrophic bog and analyzed using energy-dispersive miniprobe multielement analyzer X-ray fluorescence and Low Background γ-ray spectrometry.

Multivariate curve resolution analysis of voltammetric data obtained at different time windows: study of the system Cd2+–nitrilotriacetic acid
Marta Torres,José Manuel Díaz-Cruz,Cristina Ariño,Bozidar S Grabaric,Romà Tauler,Miquel Esteban +5 more
TL;DR: In this paper, the system Cd2+−nitrilotriacetic acid (NTA) has been studied by voltammetric techniques with different time windows (long drop time direct current polarography, differential pulse polarography and differential pulse anodic stripping voltammetry), in a way that, depending on the technique, the 1:1 complex behaves mainly labile or mainly inert.

Metal Speciation: Concepts, Analysis and Effects
Laura Sigg,Hanbin Xue +1 more
TL;DR: In this paper, the free aquo metal ion concentration, that is a key parameter for the effects of metals, is regulated by the complex interactions between trace metal ions, ligands and major ions.
Journal ArticleDOI
Understanding what we are measuring: standards and quantification of natural organic matter.
TL;DR: The case of natural organic matter types is discussed here for four different categories: carbohydrates, thiols, TEP (transparent exopolymers), and humic substances in freshwaters, where the results obtained are noticeably dependent on the standard, though the type of dependency varies.

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.

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.
