Penentuan Sifat Magnetik Dan Struktur Partikel Oksida Besi Α-Fe2o3 Dan Aplik…

Iron oxide particles contained in iron sand has the potential to be applied as catalyst in methylene blue degradation process. Magnetic iron oxide particles such as hematite (α-Fe2O3), maghemite (γ-Fe2O3) and magnetite (Fe3O4) are constituents of the iron sand. Iron oxide particles on magnetic nanoparticles has superparamagnetic properties. Iron oxide particles can be used as a catalyst i…
