Abstract
The potential use of modified clays in the adsorption of vapor phase benzene and toluene was investigated. The modified clays OC-CPC, IOC, and Al-PILC were prepared for comparative purposes and were characterized using infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction. It was confirmed the intercalation of the aluminium pillar in IOC and Al-PILC, as well as the introduction of cetylpyridinium. The adsorption studies showed a great affinity of benzene and toluene for OC-CPC due to the hydrophobic character that resulted and also to the increase in the interlaminar distance. IOC showed a lower affinity for the benzene and toluene, followed by Al-PILC. Natual clay had no affinity for benzene and toluene due to its hydrophilic nature. Clay materials having a laminar structure can be chemically modified, changing their physiochemical characteristics, such as interlaminar distance, surface area, pore size, and chemical affinity. In this study, it was focused on obtaining modified clays to be used for the adsorption of volatile organic chemicals.
