TL;DR: In this paper, a titrated iron(III) nitrate solution of varying concentration was titrated with base (NaOH) over a temperature range (24 to 90°C) by means of a homogeneous injection technique.

TL;DR: In this article, the aging process may be divided into two stages: (a) hydrolysis, polymerization leading to oxolation, nucleation, and growth to small particles (∼40 A) (b) aggregation to larger particles (200−500 A), and anisotropic flocculation to linear chains followed by slow sedimentation.
90 citations
TL;DR: In this article, the influence of sulfate ions on the formation of an iron(III) oxide phase of colloidal size was studied by homogeneous titration of acidified iron (III) solutions with varying SO4/Fe ratios (0−2.4).
61 citations
TL;DR: By homogeneous injection of alkali (NaOH) in acidified Fe(III) solutions of varying Cl Fe ratios (0, 12.8) the formation of a ferrioxyhydroxide phase of colloidal proportions was studied as discussed by the authors.
51 citations
TL;DR: In this paper, two growth models are applied in the analysis of the kinetic data, which permits an estimation of the interfacial tension of the solid to be made in acid solutions.

TL;DR: In this article, the As and Fe K-edges were collected from samples of two-line ferrihydrite with adsorbed (ADS) and coprecipitated (CPT) arsenate prepared over a range of conditions and arsenate surface coverages.
1,123 citations
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.
978 citations
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.
966 citations
TL;DR: In this paper, a study of U(VI) adsorption by ferrihydrite was conducted over a wide range of U (VI) concentrations, pH, and at two partial pressures of carbon dioxide.
