“…Other reports have also indicated the potential for recycling the used sorbent on other synthetic sorbents. The b-cyclodextrin oilabsorbents made by Ding et al [19] were reusable. The oil can be desorbed by a chemical extraction method [19].…”

a b s t r a c tIn the present study, a magnetic nanofibrous composite mat composed of polystyrene (PS)/polyvinylidene fluoride (PVDF) nanofibers with selective incorporation of iron oxide (Fe 3 O 4 ) nanoparticles (NPs) on/in PS was successfully prepared via a facile two-nozzle electrospinning process for oil-in-water separation. Field emission scanning electron microscopy and infrared spectroscopy showed the mats to be highly-porous in structure and confirmed the presence of the Fe 3 O 4 NPs on/in the nanofibers. Both PS and PVDF nanofibers exhibited oleophilic and hydrophobic properties. The results showed improved mechanical properties when PVDF was added to the composite mat compared to the pristine PS mat. In addition, the incorporation of magnetic Fe 3 O 4 NPs in the composite mat helps in the easy recovery of the mats after the oil-in-water sorption process. The composite mats showed good oil sorption capacity (35 e46 g/g) and improved mechanical property. The present electrospun magnetic PVDF/Fe 3 O 4 @PS nanofibers could be potentially useful for the efficient removal of oil in water and recovery of sorbent material.

“…Even greater benefits, in terms of oil sorption capacity, have been demonstrated when cellulosic structures have been derivatized with longerchain alkyl groups (Ball 1973;Maurin et al 1999;Deschamps et al 2003a,b;Ludwick et al 2003;Dankovich and Hsieh 2007;Said et al 2009;Cervin et al 2012) or with oilloving cyclodextrins (Ding et al 2011;He et al 2012). Rosin, a hydrophobic agent that is often used to reduce the water-absorptivity of paper, has been shown also to improve the ability of papermaking fibers to take up oil (Ericsson 1985).…”

“…Compared with olefins, alkyl acrylates are more popular monomers because of their abundant sources and low price. [10][11][12] The oil absorption polymers are usually in the form of bulk or microspheres. In theory, the oil-absorbent microspheres have the advantages of convenient transportation and excellent oil absorption performance because of their small volume and large specific surface area [9,13] .…”

A novel type of porous oil-absorbent microspheres based on poly(stearyl methacrylate-co-butyl acrylate) was prepared via suspension polymerization. By investigating the effects of the cross-linking agent, monomer ratio, initiator, stabilizer, water/oil ratio, and porogen agent on the oil absorbency of the prepared oil-absorbents, an optimized oil-absorbent microsphere OAM-T was obtained, and characterized by FT-IR and SEM. The oil absorbencies of OAM-T toward chloroform, toluene, gasoline, and diesel were measured to be 61.9, 32.6, 28.8, and 28.2 g/g respectively, with oil absorption saturation time being 1.0, 1.5, 2.0, and 3.0 hr. The oil retention of OAM-T toward the four oils is all above 95%. Besides in pure oils, OAM-T also has high oil absorbencies in oil-water mixture. It can be reused at least 12 times with little change in oil absorbency. Owing to its excellent oil absorption performance, OAM-T might find applications for removing oil spills and organic pollutants from water.
