In situ study of the goethitehematite phase
tite derived from goethite retains hydroxyls and a lack of iron with respect to stoichiometric hematite They proposed for this phase the following chemical formula: α Fe 2 x/3 (OH) xO 3 x with x = number of residual hydroxyls in the structure The iron deficiency was detected by measurement of the integrated intensities of certain powder peaksThe dissolution of goethite in aqueous media containing EDTA, Fe(II), and Fe(III) has been studied The main dissolution pathways involve the inner or outer sphere electron transfer in mixedvalence EDTAbridged surface complexes and in surface “ion pairs” A synergistic effect is observed between ferrous EDTA and free EDTAThe Influence of Iron (II) and (III) on the Kinetics of The development of particle morphology and crystalline structure during the dehydration, oxidation, and reduction processes of goethite to iron needles was investigated by HREM It is shown that the typical geometry of the particles is preserved during all transformation steps, and that initial internal defects of the crystalline structure caused by twinning of the goethite vanish, while some new defects The effect of dendritic shapes of goethite particles on
