Background: Nanotechnology is a new approach that has been lionized in recent years. One of its applications is its consumption as an absorbent. In this study, the single-wall carbon nanotubes (SWCNTs) were used as an absorbent for sampling benzene in the air. Materials and Methods: For this study, SWCNTs manufactured by Iran and SKC’s activated charcoal were used for sampling benzene vapors....
