Abstract
In this scientific research, magnesium oxide (MgO) nanoparticles were synthesized from magnesium nitrate and ammonium solutions via microwave@sol-gel process. The structure and the morphology of the synthesized nanoparticles has been identified and characterized by X-ray diffraction (XRD), N2-BET (Brunauer-Emmett-Tell), scanning electron microscopy (SEM) and fourier transform infrared (FTIR) techniques. The crystallite size of nano MgO was in the range of (100 nm (and surface area of 596.39 m2/g. The (2-chloro ethyl phenyl sulfide) 2-CEPS are a sulfurous pollutant. This compound can cause the contaminations of environment. In this survey, we used MgO nanoparticles for removal of 2-CEPS molecule. The results of UV/Vis irradiation for the weight ratio of 1:40 (2-CEPS: MgO nanoparticles) at ambient temperature emphasized that 2-CEPS molecule has the highest amount of removal about 61% and 70% by nanoparticles in the isopropanol and n-heptane solvents after 8 hours, respectively. Although, for the weight ratios of 1:10, 1:20 and 1:30 very lower degradation of the sulfurous pollutant (from the same conditions) was observed. Elimination single product; i.e. phenyl vinyl sulfide (PVS) has been identified via GC-MS analysis.
