An electrochemical sequential injection method to investigate the adsorption of selenite on Fe(III) polyhydroxy cations intercalated vermiculite
TL;DR: A sequential injection - square wave anodic stripping voltammetry method for determination of Se(IV) at a gold working electrode was developed and adsorption onto vermiculite intercalated with Fe(III) polyhydroxy cations was investigated, finding its capacity was higher than that found for several other iron oxides, but lower than that obtained for oxide/hydroxide-based Fe( III) nanoparticles.

Kinetic Speciation of Ni(II) in Model Solutions and Freshwaters: Competition of Al(III) and Fe(III)
TL;DR: In this paper, the competitive binding of Ni(II) by Al(III) and Fe(III), in model aqueous solutions and freshwaters, was investigated, and the results showed that Ni(2)-humate complexes were more labile in the presence of the mixture of Al(3) or Fe(3).
Journal ArticleDOI
A comparative study of polyelectrolyte effects and conformational changes in several purine and pyrimidine homopolyribonucleotides
TL;DR: A comparative study of the acid-base and copper(II) complex-forming properties of homopolyribonugleotides polyuridylic acid, polyinosinic acid and polycytidylic acids has been carried out in this article.
Journal ArticleDOI
Effects of weak organic acids on the size distribution and size-dependent metal binding of humic substances as studied by flow field-flow fractionation
Yuji Yamashita,Takumi Saito +1 more
TL;DR: In this paper, the effects of low molecular weight weak organic acids, which are commonly used as pHbuffering agents, on the hydrodynamic size of purified Aldrich humic acid (PAHA) at pH 7 were investigated by means of flow field flow fractionation.
Journal ArticleDOI
Use of fluorescence spectroscopy and voltammetry for the analysis of metal-organic matter interactions in the New Caledonia lagoon
TL;DR: In this article, fluorescence, polarographic and potentiometric analysis of sea water from the New Caledonia lagoon (located south of Noumea) allowed the determination of the specific properties of the dissolved and particulate phases of organic matter (OM)-metal complexes according to various regions of the lagoon.

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.
