nucleophilic chemistry of the synthesized magnesium oxide (magnesia) nanoparticles via microwave@sol-gel process for removal of sulfurous pollutant
نویسندگان
چکیده
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.
