Separation of copper (II) ions from humic complexes with oxine-impregnated emulsion globules
Masataka Hiraide,Koh Hasegawa +1 more
TL;DR: A water-in-oil type emulsion containing oxine has been used for the discrimination of copper(II) ions and copper-humic complexes in aqueous solutions as discussed by the authors.
Journal ArticleDOI
Metal distribution and binding in balneological peats and their aqueous extracts.
TL;DR: Investigations of the peat extracts using tangential-flow ultrafiltration revealed that the heavy metals extracted at pH < 4 were predominantly dissociated and at higher pH (pH > 4.5) they were preferentially bound to macromolecular DOM.
Journal ArticleDOI
Stripping chronopotentiometry at scanned deposition potential (SSCP). Part 6. Features of irreversible complex systems
TL;DR: In this paper, the shape of the SSCP wave is dependent on the value of k0, the deposition time and the electrode size, and the stability of a metal complex can be determined from the shift in half-wave deposition potential, Ed,1/2.
Journal ArticleDOI
Distribution of Minor and Trace Metals in Carezza Lake (ANTARCTICA) Ecosystem
TL;DR: In this article, the distribution of a series of metals in natural samples collected at Carezza Lake in Antarctica, during the Italian Expedition in the austral summer 1989/90, was reported.
Journal ArticleDOI
Soil-washing design methodology for a lead-contaminated sandy-soil
TL;DR: In this article, a double layer surface complexation model was used to describe equilibrium sorption behavior and a preliminary design of an ex-situ countercurrent equilibrium stage extraction process was presented.

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.
Journal ArticleDOI
Ecosystem dynamics based on plankton functional types for global ocean biogeochemistry models
Corinne Le Quéré,Sandy P. Harrison,Sandy P. Harrison,I. Colin Prentice,I. Colin Prentice,Erik T. Buitenhuis,Olivier Aumont,Laurent Bopp,Hervé Claustre,Leticia Cotrim da Cunha,Richard J. 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.
