Hematite nanopowder obtained from waste: Iron

Abstract X-ray diffraction and Fourier-transform IR spectroscopy techniques were employed to confirm that heavy-tonnage iron-removal sludge wastes could be successfully used to synthesize hematite nanopowder (HM NP) with an average particle size of 42 nm. The sizes of the HM NP particles were confirmed from the TEM images.
