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.
