Abstract
Multi-walled carbon nanotubes impregnated with Fe2O3 nanoparticles were prepared. The multi-walled carbon nanotubes were used to remove benzene from water. The iron-impregnated carbon nanotubes from a range 5 wt% iron to 20 wt% iron were prepared. The removal of benzene increases with the increase of impregnated iron percent in the multi-walled carbon nanotube. Redlich-Peterson model gives better data representation. Maximum adsorption capacity of impregnated CNTs was found to be 271 mg/g. The highest adsorption capacity of carbon nanotubes impregnated by iron nanoparticles confirms a good possibility to be an excellent adsorbent compared to others adsorbents to remove benzene from water.
