摘要：

Structural analysis techniques such as X-ray diffraction and anomalous X-ray scattering were used for characterizing the influence of manganese on iron oxyhydroxides and oxides formed from green rust (GR) in an aqueous solution. The results showed that the formation of Fe3O4 was enhanced by the addition of manganese ions during the conversion of GR2(SO42-) to alpha-FeOOH and Fe3O4. The results obtained from anomalous X-ray scattering showed that manganese was present both in alpha-FeOOH and Fe3O4 particles. The incorporation of manganese in alpha-FeOOH appears to induce the distortion of the atomic-scale structure of alpha-FeOOH particles formed in an aqueous solution. (C) 2007 Elsevier Ltd.
