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.

制备了浸渍有Fe ₂ O ₃纳米颗粒的多壁碳纳米管。使用多壁碳纳米管从水中去除苯。制备了铁含量为5重量％至20重量％的铁浸渍的碳纳米管。苯的去除随着多壁碳纳米管中铁含量的增加而增加。Redlich-Peterson模型可提供更好的数据表示。发现浸渍的CNT的最大吸附容量为271mg / g。铁纳米颗粒浸渍的碳纳米管的最高吸附能力证实，与其他从水中除去苯的吸附剂相比，它是极好的吸附剂。
