The effect of the pH values on the nucleation of ferric oxyhydroxide and oxide phases in aqueous solutions of iron salts is analysed using partial charge theory. As experimentally shown, at pH in a range of 6.0–6.5, the nucleation of the β-FeOOH phase occurs, while at pH=10.5–11.0, the magnetite phase is formed. The structural and morphological properties of the obtained ultrafine iron compounds are analysed by x-ray diffraction analysis, adsorption porosimetry, and Mössbauer spectroscopy [ABSTRACT FROM AUTHOR] |
