Geochemische Stoffkreisläufe in Binnenseen: Akkumulation versus Remobilisierung von Spurenelementen
TL;DR: Agarwal et al. as discussed by the authors show that aquatische Okosysteme reagieren sehr empfindlich auf anthropogene Veranderungen and sind sensible Indikatoren fur die Belastung unserer Umwelt.

Complexation parameters of heavy metals by olive mill wastewater determined by a cation exchange resin
M. Bejarano,L. Madrid +1 more
TL;DR: In this article, the maximum complexing ability (MCA), the stability constant (Kc) and a parameter indicating the stoichiometrical characteristics of the complex were estimated using a cation exchange resin method.
Journal ArticleDOI
Voltammetric determination of stability constants of lead complexes with diallyl disulfide, dimethyl disulfide, and diallyl sulfide
TL;DR: In this paper, the formation of 1:1 and 1:2 complexes with DADs, DMDS, and DAS was studied by differential pulse voltammetry and the stability constants were found to be in the range of 3.8-4.2 and 9.4-10.2, respectively.
Speciation of Heavy Metals in Sediments Sampled from Different Pollution Sources of Lake Dang, Ngaoundere-Cameroon
TL;DR: In this paper, the speciation of five trace metallic elements (Cr, Pb, Ni, Zn, Cu) in sediments from Lake Dang Ngaoundere Cameroon was carried out by the sequential extraction technique.
Journal ArticleDOI
Application of potentiometric stripping analysis for speciation of copper complexes with a non-adsorbable ligand on a mercury electrode.
TL;DR: Glycine was used as a model of a non-adsorbable ligand on the mercury electrode that forms well defined 1:1 and 1:2 copper(II)-glycine complexes, which are labile within the time scale of the analytical technique.

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.

Ecosystem dynamics based on plankton functional types for global ocean biogeochemistry models

Geider,Xavier Giraud,Christine Klaas,Christine Klaas,Karen E. Kohfeld,Louis Legendre,M. Manizza,M. Manizza,Trevor Platt,Richard B. Rivkin,Shubha Sathyendranath,Julia Uitz,Andrew J. 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.
