Catalytic activity of using tungsten oxide with hydrogen peroxide for methyl orange degradation

In this work, a tungsten oxide nanoparticle was developed with a simple method, using tungsten powder. The orthorhombic, hexagonal and monoclinic crystalline structures obtained were characterized by X-ray diffraction, scanning electron microscopy, as well as Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The coupling of these tungsten oxide nano particles with hydrogen peroxide is carried...

Preparation, characterization of raw corncob adsorbent for removal of heavy metal ions from aqueous solution using batch method

Corncob adsorbent was prepared through environmental friendly process without any additional chemical treatment. The prepared material was characterized by X-ray diffract meter (XRD), Fourier transform infrared spectroscopy (FTIR) and pH points zero charge techniques. The XRD diffracted pattern of corncob adsorbent did not shows well-defined sharp peaks instead it shows pumps peaks; this indicates that the diffraction...
