摘要
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). During titration the optical density of the solution was continuously recorded. Solid phase analysis was performed by means of X-ray and Mössbauer spectroscopy. An analysis of the experimental results shows that the role of the sulfate ion is rather complex. The process of the nucleation and growth of the iron oxyhydroxides is described and the influence of sulfate on the various stages in that process is discussed. Certain stages are catalyzed by the sulfate ions, whereas other stages are suppressed. © 1979.
