Interactions of calcium and fulvic acid at the goethite-water interface
TLDR
In this article, the mutual influence of the interactions on the adsorption of fulvic acid, calcium ions and protons was examined with batch and titration experiments with the Ligand and charge distribution (LCD) model.About:

TL;DR: A general description of the mathematical and numerical formulations used in modern numerical reactive transport codes relevant for subsurface environmental simulations is presented, along with a selective list of applications that highlight their capabilities and historical development.
Journal ArticleDOI
Biodegradation of forest floor organic matter bound to minerals via different binding mechanisms
TL;DR: In this paper, the authors studied the biodegradation of OM bound to goethite (α-FeOOH), pyrophyllite, and vermiculite via specific mechanisms as estimated from OC uptake in different background electrolytes and operationally defined as 'ligand exchange', 'Ca2+ bridging', and 'van der Waals forces'.
Journal ArticleDOI
Isoelectric points and points of zero charge of metal (hydr)oxides: 50years after Parks' review.
TL;DR: The present paper is an up-to-date compilation of the values of PZC and IEP of metal oxides, and new methods and correlations found over the recent 50years are presented.
Journal ArticleDOI
Multi-competitive interaction of As(III) and As(V) oxyanions with Ca2+, Mg2+, PO3−4, and CO2−3 ions on goethite
TL;DR: Data as well as calculations show the dominance of phosphate in regulating the As concentrations, and the thus calibrated model is able to predict successfully the ion concentrations in the mixed 2- and 3-component systems as a function of pH and loading.

Surface Complexation Modeling: Hydrous Ferric Oxide
TL;DR: In this article, the generalized two-layer model is used to analyze the Coulombic effect of Hydrous Ferric Oxide, and anion and cation sorsption on HFOs are investigated.
Journal ArticleDOI
Adsorption and desorption of natural organic matter on iron oxide: mechanisms and models.
TL;DR: Results indicated that ligand exchange between carboxyl/hydroxyl functional groups of NOM and iron oxide surfaces was the dominant interaction mechanism, especially under acidic or slightly acidic pH conditions.
