An attempt has been made to utilize nanoparticles of iron oxide, obtained as waste from the Cold Rolling Mill (CRM) of an integrated steel company, to remove arsenite (As 3+ ) from arsenic contaminated water. The iron oxide fines from the CRM were characterized with regard to their composition, phase, morphology and magnetic properties and capacity to adsorb arsenite. The major component of...
Magnetite nanoparticles were applied to remove Cu (II) from aqueous solutions. The highly crystalline nature of the magnetite structure with a diameter of around 10nm was characterized with transmission electron microscopy (TEM) and X-ray diffractometry (XRD). The surface area was determined to be 115.3m 2 /g. Surface chemical properties of magnetite at 25°C in aqueous suspensions were investigated...
