Characteristics of aniline and nitrobenzene adsorption on single-walled, multi-walled and graphitized multi-walled carbon nanotubes

摘要

Herein, we assess the relative potential of single-walled, multi-walled and graphitized multi-walled carbon nanotubes (CNTs) for the adsorptive removal of organic species using aniline and nitrobenzene as model aromatic contaminants. The obtained results reveal that the adsorption behaviour of aromatic organics is significantly affected by their functional groups (especially when functionalized CNTs are used as adsorbent), providing valuable guidance for adsorption-based removal of organic contaminants from the environment.
