Hydrolysis-precipitation studies of iron solutions. I. Model for hydrolysis and precipitation from Fe(III) nitrate solutions

J. Dousma, +1 more
- 01 Sep 1976 - 
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.
Journal ArticleDOI

Hydrolysis—precipitation studies of iron solutions. II. Aging studies and the model for precipitation from Fe(III) nitrate solutions

J. Dousma, +1 more
- 15 Mar 1978 - 
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.
Journal ArticleDOI

The influence of sulfate ions on the formation of iron(III) oxides

J. Dousma, +2 more
- 01 Jan 1979 - 
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).
Journal ArticleDOI

The influence of chloride ions on the formation of iron(III) oxyhydroxide

J. Dousma, +2 more
- 01 Jan 1978 - 
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.
Journal ArticleDOI

Hydrolysis—precipitation studies of iron solutions: III. Application of growth models to the formation of colloidal αFeOOH from acid solutions☆

J. Dousma, +1 more
- 01 Nov 1979 - 
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.
