| dc.description | In wastewater treatment facilities, air quality is not only affected by conventional unpleasant odour
compounds; toxic volatile organic compounds (VOCs) are also found. In this study, the adsorptive
capacity of Chilean natural zeolite toward VOC removal was evaluated. Moreover, the influence of
zeolite chemical surface properties on VOC elimination was also investigated. Three modified zeolite
samples were prepared from a natural Chilean zeolite (53% clinoptilolite, 40% mordenite and 7%
quartz). Natural and modified zeolite samples were characterised by nitrogen adsorption at 77 K,
elemental analyses and X-ray fluorescence (XRF). Chemical modifications of natural zeolite showed
the important role of Brønsted acid sites on the abatement of VOCs. The presence of humidity has a
negative effect on zeolite adsorption capacity. Natural zeolites could be an interesting option for
benzene, toluene and xylene vapour emission abatement | |
