TL;DR: In this paper, the effects of changes in ionic strength on the adsorption behavior of selenite and selenate on goethite and hydrous ferric oxide have been modeled using a generalized version of the triple-layer surface complexation model.

TL;DR: In this paper, three triple-layer model (TLM) surface complexation models that allow for the formation of multinuclear surface complexes or precipitates are compared, based on their ability to simulate cobalt sorption on α-Al2O3.

TL;DR: In this article, in situ extended x-ray absorption fine structure (EXAFS) measurements of adsorbed selenate and selenite ions at the α-FeOOH(goethite)-water interface have been performed; these measurements show that selenates forms a weakly bonded, outer-sphere complex and that Selenite forms a strongly bonded, inner-spheres complex.

TL;DR: The ability of surface complexation models (SCMs) to fit sets of titration data as a function of changes in model parameters was evaluated using FITEQL and acid-base data of α-FeOOH, α-Al2O3, and TiO2 as discussed by the authors.

TL;DR: This volume includes 32 papers which were presented at a symposium on geochemical processes at mineral-water interfaces in 1985 and which bring to bear on this area a very wide range of expertise as discussed by the authors.
