제목 Magnesium oxide and magnesium aluminate nanoparticles as a promising adsorbent for the removal of some organic dyes
초록 Magnesium oxide (MgO) and magnesium aluminate (MgAl2O4) nanostructures were synthesized via a sol-gel combustion method using urea, oxalic acid, and citric acid fuels. The effect of the fuel type on the products was studied. The as-prepared products were characterized by means of powder X-ray diffraction, Fourier transform infrared, transmission electron microscope and scanning electron microscope. The oxalic acid fuel produced pure MgO nanoparticles with the smallest crystallite size (ca. 12 nm) while urea fuel produced pure MgAl2O4 nanoparticles with the smallest crystallite size (ca. 14.6 nm). These two oxides were used as adsorbent for the removal of Reactive Red 195 (RR195) and Orange G (OG) dyes. The different parameters that can affect on the adsorption process were studied. In addition the adsorption isotherm, rate determining kinetic and thermodynamic models are applied for the investigation of adsorption behavior.
