“…As reported, estimated deposits of Ca-bentonite alone consist of 2.5 billion tons of material in the global world. The cost ($ 40 t -1 ) of nature clays is much cheaper than that of AC (Morozov et al, 2014;Qu et al, 2009). The large surface area, unique combined micro-and mesoporosity and fast mass transfer rates make clay become a potential adsorbent for VOCs abatement.…”

“…If the VOCs such as benzene, n-hexane and methanol have the similar monolayer volumes, porous adsorbents have no selectivity in the separate adsorption of each component and show almost adsorption capacity (Morozov et al, 2014). The adsorption process of binary or multicomponent VOCs vapors on porous adsorbents is more complicated.…”

“…However, except for competitive adsorption, the cooperative adsorption between water and hydrophilic or water miscible VOCs existed under some certain conditions. Morozov et al (2014) compared the adsorption performance of montmorillonites for benzene, n-hexane and methanol in the presence of water. The adsorption capacity of hydrophobic VOCs (benzene and n-hexane) showed a significant decrease as the increasing relative humidity from 26% to 100%.…”

Volatile organic compounds (VOCs) have attracted world-wide attention regarding their serious hazards on ecological environment and human health. Industrial processes such as fossil fuel combustion, petrochemicals, painting, coatings, pesticides, plastics, contributed to the large proportion of anthropogenic VOCs emission. Destructive methods (catalysis oxidation and biofiltration) and recovery methods (absorption, adsorption, condensation and membrane separation) have been developed for VOCs removal.Adsorption is established as one of the most promising strategies for VOCs abatement thanks to its characteristics of cost-effectiveness, simplicity and low energy consumption. The prominent progress in VOCs adsorption by different kinds of porous materials (such as carbon-based materials, oxygen-contained materials, organic polymers and composites is carefully summarized in this work, concerning the mechanism of adsorbate-adsorbent interactions, modification methods for the mentioned porous materials, and enhancement of VOCs adsorption capacity. This overview is to provide a comprehensive understanding of VOCs adsorption mechanisms and up-to-date progress of modification technologies for different porous materials.

“…The result of adsorption confirmed that the adsorbent had the ability to remove hydrogen sulfur and the capacity was 39.2 mg g-1. In another study, Morozov et al (2014) studied the sorption of volatile organic compounds (VOCs) such as n-hexane, benzene, and methanol on K-10 montmorillonite. The adsorption results of dried adsorbent (dried in oven at 250 °C) showed that adsorbent could remove benzene and nhexane from the system and the amounts obtained at P/P0 =0.4 were 179 and 185 µg L -1 (Morozov et al, 2014).…”

Natural bentonite was modified with zinc ions and was used as a filler to reduce the offensive odor from raw natural rubber (NR). Characterization of filler shows the limited exchange of inherent calcium ions and the preferred adsorption of zinc ions on the surface of natural bentonite during modification. e modification process was also accompanied by bassanite formation due to sulfate ions brought by the zinc salt. Zinc-modified bentonite demonstrates an antimicrobial effect against microorganisms that are known to degrade or produce offensive odor from raw NR. Due to its antimicrobial and adsorption properties, zinc-modified bentonite significantly reduces the offensive odor from raw NR at loadings of 2.5-7.5 phr as shown by the olfactometry test. In terms of vulcanization characteristics, the loading of zinc-modified bentonite at 7.5 phr caused a slight decrease in elastic torque and increase in scorch and curing times of NR. e hardness and tensile properties of vulcanized NR are maintained after compounding with zinc-modified bentonite at 7.5 phr.
