Abstract
Silica nanoparticles have been successfully synthesized by utilizing sol-gel auto-combustion method using fuels (oxalic acid and citric acid) followed by the calcination at 850 oC for 4 h. The fabricated silica nanoparticles were characterized by various tools such as X-ray diffraction (XRD), Fourier transform infrared analysis (FT-IR), Field-emission scanning electron microscope (FE-SEM) and high-resolution transmission electron microscope (HR-TEM). The batch adsorption was applied for the removal of sun set dye over the fabricated silicon oxide adsorbent under various experimental conditions. The extracted adsorption data were examined using some adsorption isotherm and kinetic models. The thermodynamic parameters were calculated for the removal of sun set dye over silicon oxide nanoparticles.
