Toluene and n-hexane are volatile organic compounds(VOCs) commonly used as solvents in the industry. VOCs can be removed by TiO2, which is an important issue in environmental science. TiO2 have been proposed for a wide range of uses including catalysis, photovoltaic cells, self-cleaning devices, and so forth. TiO2 is inexpensive, non-toxic, resistant to photo-corrosion, and has high oxidative power. TiO2 occurs mainly in three different crystallines, which are anatase, rutile, and brookite. On the other hand amorphous TiO2 is of interest for adsorption because of its high surface area and high adsorptivity. Moreover, simple synthesis with elimination of the calcination step would mean lower costs for chemicals and energy consumption. In this study, the adsorption of toluene and n-hexane on TiO2(amorphous TiO2, hybrid TiO2(amorphous/crystalline), anatase TiO2) were carried out in order to compare their adsorptivities. The TiO2 particles were characterized using XRD, and BET. |
