A Comparative Study on Sorption of As (V) ions on Hematite, Goethite and Magnetite Nanoparticles

Adegoke H.I., Adekola F.A., Fatoki O.S., Ximba B.J., University of Ilorin, NG

Hematite (-Fe2O3), magnetite (Fe3O4) and goethite (-FeOOH) nanoparticles were synthesized by transformation of ferrihydrite and precipitation methods, this materials were used for the removal of arsenic (V) ions from aqueous solution. The synthesized nanoparticles were [...]

Nanoporous Materials through Anodizing of Iron in F-containing Organic Electrolytes

Jagminas A., Mažeika K., Klimas V., State research institute Center of physical sciences and technology, LT

In this brief review, our recent progress in fabrication, characterization and application of thick nanoporous iron anodic films in ethylene glycol and a novel dimethyl sulfoxide (DMSO) electrolyte containing some fluorides will be presented and [...]

Magnetic nanoparticles with variable size and shape and surface functionality as switchable building blocks for soft nanotechnology

Dietsch H., Malik V., Reufer M., Schurtenberger P., Fribourg Center fro Nanomaterials, FriMat, CH

Alpha-Fe2O3 (hematite) particles can be synthesized by forced hydrolysis of iron salts. The chosen iron salt dissolves and leads to a first crystalline structure called akaganeite (Beta-FeOOH), which, reorganized and combined with more iron precursor [...]
