Outline of Final Research Achievements

Ferrihydrite as hydrous ferric oxyhydroxide (Fe2O3・0.5H2O) is widespread mineral in environment of the earth’s surface, and can be regarded as important absorbent for trace elements and heavy metals in ground water and soil. However, the medium range order of atomic arrangement in ferrihydrite which is closely related to the physicochemical properties has not been revealed yet. In this study, we demonstrate the structural study of ferrihydrite by state of art AXS-RMC method, coupling of anomalous X-ray scattering and reverse Monte-Carlo simulation.
