Abstract: The retention of hazardous species, including many of the lanthanides, on soils and sediments is vital for maintaining environmental quality. In this study, high-resolution transmission elec...
Influence of Manganese Oxide Minerals on the Formation of Iron Oxides
Akaganeite Cryptomelane Feroxyhyte Hausmannite Iron oxides Manganese Oxidation-reduction Pyrolusite Synthesis
2012/1/10
The influence of manganese oxide minerals (cryptomelane, hausmannite, and pyrolusite) on the formation of iron oxides was studied in the FeCl2-NH4OH system at different Mn/Fe molar ratios (0, 0.01, 0....
