Journal ArticleDOI
Electrochemical investigations of the effect of N-substituted aminosulfonic acids with a piperazinic ring pH buffers on heavy metal processes which may have implications on speciation studies
TL;DR: In this paper, the influence of piperazine-N,N′-bis(2-ethanesulfonic acid) (PIPES), N-2-hydroxyethylpiperazine N′- 2-ethane sulfonic acid (HEPES), and N-hydroxethylpernazine-n′-2 -hydroxypropanesulfonic acyclic acid(HEPPSO) on the redox processes of cadmium, lead and zinc was investigated by differential pulse anodic stripping voltammetry (DPASV
Journal ArticleDOI
Preliminary toxicity assessment of water after treatment with UV-irradiation and UVC/H2O2
TL;DR: Toxicity was not apparent for both the Microtox procedure and cytotoxicity analyses for the UVC-irradiated and UVC/H2O2-treated NOM samples, while UVA- and UVB-IRradiated water samples were non-toxic to D. carinata.
Journal ArticleDOI
Fe, Al and Si species and organic matter leached off a ferrallitic and podzolic soil system from Central Amazonia
TL;DR: In this article, the geochemistry of soil formation in central Amazonia, Brazil, was investigated by studying the waters draining off small podzolic, ferrallitic or mixed catchment areas.
Journal ArticleDOI
Multi-method Study on Aquatic Humic Substances from the "Rio Negro" - Amazonas State/Brazil: Emphasis on Molecular-Size Classification of their Metal Contents
TL;DR: The aquatic humic substances investigated in this paper were conventionally isolated from Rio Negro waters - Amazonas State/Brazil by means of the collector XAD 8 as mentioned in this paper, using a five-stage tangential-flow ultrafiltration (UF) device.
Journal ArticleDOI
Use of a polarographic method to determine copper, nickel and zinc constants of complexation by extracellular polymers extracted from activated sludge
TL;DR: In this article, the constants of complexation of extracellular polymers (ECPs) extracted from sludges for three metals, Cu, Ni and Zn at pH 7, were determined using a polarographic method (stripping mercury dropping electrode mode).

Journal ArticleDOI
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.

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.
