Abstract

SnO2 nanoparticles have been formed using chemical precipitating method and the resulting particles were then investigated by FESEM (field emission scanning electron microscopy), TEM (transmission electron microscopy), and Fourier-transform infrared spectroscopy (FT-IR).The crystal structure and the grain size were deduced from X-ray diffraction pattern. The band gap energy was calculated from UV-Vis spectrum and it was 3.7 eV, this redshift comparing to bulk SnO2 could attributed to the quantum effect. The adsorption behavior of SnO2 Nano crystals was tested with mefenamic acid (MFA) in aqueous solutions. Different certain parameters as pH, MFA concentration, temperature, studying time and adsorbent dosage to determine the best adsorption conditions. It was found that the maximum removal efficiency is 92.6% when the concentration of MFA and dosage of SnO2 were 30 mg/L and 0.6 g, respectively, within 80 minutes. The MFA adsorption mechanism is consistent with the Freundlich isotherm models.SnO2 nanoparticles have been formed using chemical precipitating method and the resulting particles were then investigated by FESEM (field emission scanning electron microscopy), TEM (transmission electron microscopy), and Fourier-transform infrared spectroscopy (FT-IR).The crystal structure and the grain size were deduced from X-ray diffraction pattern.
