Original Paper


An adsorbent-based acrylonitrile-co-butadiene-co-styrene, polyacrylonitrile and lead nanoparticles blend were prepared using electrospinning process. Its application was investigated for the removal of sulfur from gasoline. The nanofiber was characterized by scanning electron microscopy, X-ray diffraction, BET and Fourier transform infrared spectroscopy. BET analysis indicated that the specific surface areas of lead-loaded nanofibers were increased with adding the content of lead nanoparticles. The results of field emission scanning electron microscopy characterization showed that the lead nanoparticles were successfully loaded on the nanofibers uniformly. Gas chromatography-mass results also revealed that lead-loaded nanofiber was a useful adsorbent for the desulfurization of gasoline. The effects of experimental parameters on the extraction efficiency of the sorbent were investigated too. The removal efficiency and adsorbent capacity were found to be 93.31%, 31.4 mg S/g, respectively, for the removal dibenzothiophene in the 10 mL n-hexane solvent.
