Toluene removal from aqueous solutions using single wall carbon nanotube and magnetic nanoparticle hybrid adsorbent

The application of single-wall carbon nanotubes (SWCNTs) in aqueous solutions is limited due to their release and inability to restrain them. Therefore, the change in their properties of carbon nanotubes through modification in order to prevent their release seems essential. This study was an attempt to cover SWCNTs by magnetic nanoparticles in order to improve the adsorption capacity and strengthen the separation of SWCNTs from an aqueous solution. At this study, the experimental design was used to optimize the parameters of toluene removal by single-wall carbon nanotubes-magnetic nanoparticles (SWCNT-MN). The maximum removal of toluene (99.6%) occurs in the optimal condition for toluene removal by SWCNT-MN nanoreactors. The obtained results in both batch and continues column modes indicate that the removal efficiency in column mode is less than batch mode. This suggests that the SWCNT-MN possessed a good potential for toluene removal from polluted aqueous solutions with controlled releasing
