Surface ionization and complexation at the oxide/water interface
TL;DR: In this article, a method for determination of intrinsic ionization and complexation constants of oxide surface sites from potentiometric titration data is reported using these experimental properties and the stoichiometry of surface reactions, surface charge, σo, adsorption density, Γi, and diffuse layer potentials, ψd, at the oxide/water interface.

Multiple-site adsorption of cd, cu, zn, and pb on amorphous iron oxyhydroxide
Mark M. Benjamin,James O. Leckie +1 more
TL;DR: In this paper, the strength of binding between a given metal and the surface may vary by an order of magnitude or more from one site to another, suggesting that the surface is composed of many groups of binding sites.

Surface ionization and complexation at the oxide/water interface II. Surface properties of amorphous iron oxyhydroxide and adsorption of metal ions
James A. Davis,James O. Leckie +1 more
TL;DR: In this paper, the site-binding model for the electrical double layer of hydrous oxides reported in a previous paper is applied to the adsorption of metal ions from dilute solution and to complex heterogeneous systems, i.e., amorphous iron oxyhydroxide.

Effect of membrane chemistry and coating layer on physiochemical properties of thin film composite polyamide RO and NF membranes I. FTIR and XPS characterization of polyamide and coating layer chemistry
TL;DR: In this article, the physicochemical properties of reserve osmosis (RO) and nanofiltration (NF) polyamide (PA) membranes are largely determined by their PA chemistry and coatings, if any.

- 01 Feb 1987
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.
