Measurement of Benzene in Air by Iranian Single-Wall Carbon Nanotubes

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. Preparation and analysis of the samples were done by carbon disulfide and GC-FID (gas chromatography-flame ionization detector), respectively Results: The results indicated that the performance of SWCNTs is less than conventional activated charcoal for sampling benzene vapors in the air Conclusion: The findings of this study showed that the performance of SWCNTs in the sampling of benzene vapors in the air is very poor and, therefore, cannot be a good alternative to SKC’s activated charcoal.
