Abstract
A novel oil highly absorptive resin was prepared by a suspension polymerization using 1-butyl -3- (2- methacryl) ethyl imidazolium hexafluorophosphate (BMIm)PF6-, methyl methacrylate (MMA), and butylacrylate (BA) as monomers, azobisisobutyronitrile as initiator, N, N methylenebis (acryl amide) (MBA) as crosslinking agent and polyvinyl alcohol (PVA) as dispersant and characterized by Fourier-transform infrared (FT-IR) spectroscopy, thermal gravimetric analysis (TGA), and scanning electron microscopy (SEM). The effects of different polymerization technological parameters, such as the mass ratios of the monomers, the addition amounts of the initiator, the cross-linker and the dispersant, the polymerization temperature and time, on the oil absorbency of the high oil absorption resin P (BMIm-MMA-BA) copolymer were examined in detail. Under the optimal condition, the oil absorbency was about 25.6 g/g for benzene, 22.6 g/g for xylene, 32.3g/g for chloroform, and 30 g/g for carbon tetrachloride, respectively. The kinetic investigation indicated the oil absorption obeyed the pseudo-first-order kinetic equation.
Highlights
Environmental pollution is becoming more and more serious at present; in particular, deterioration of water quality of ocean, river and lake polluted by oil and oil-like organic solvents is one of the most calamities for human, animal, halobios, and plant
Various materials, including natural absorbents and synthesized polymeric materials, have been developed to deal with oil pollution hazards and recover the spilled oils [1,2,3,4,5,6,7], and oil-absorbing resin have been used widely to absorb oil spilled on water
The removal performance of the prepared high oil absorption to several organic compounds was examined and the influencing factors on the oil absorbency of the high-oil-absorption resin were studied in detail including the monomers mass ratio, water/oil mass ratio, amounts of the cross-linking agent and initiator, type and amount of dispersing agent, and polymerization temperature
Summary
Environmental pollution is becoming more and more serious at present; in particular, deterioration of water quality of ocean, river and lake polluted by oil and oil-like organic solvents is one of the most calamities for human, animal, halobios, and plant. Xu et al [12] used methyl methacrylate (MMA), butyl methacrylate (BMA), and hydroxyl ethyl methacrylate (HEMA) as monomers to synthesize an oil-absorbing resin through a suspension polymerization. Fathelrahman Mohammed Soliman et al.: Synthesis and Characterization of an Ionic Liquid Enhanced High Oil. Absorption Resin of P (BMIm-MMA-BA) and Its Oil Absorption Performance initiated suspension copolymerization, and N, Nmethylenebis (acrylamide) as crosslinking agent, and polyvinyl alcohol as dispersant and a high absorbency to chloroform was obtained 38.1 g/g. The removal performance of the prepared high oil absorption to several organic compounds (oil contaminations) was examined and the influencing factors on the oil absorbency of the high-oil-absorption resin were studied in detail including the monomers mass ratio, water/oil mass ratio, amounts of the cross-linking agent and initiator, type and amount of dispersing agent, and polymerization temperature
