Abstract
A highly oil-absorptive Poly (methyl methacrylate-butyl acrylate)/ ATP–Fe3O4 magnetic composite resin was prepared by a conventional suspension polymerization using methyl methacrylate, and butylacrylate were used as monomers, and N, N-methylenebis acrylamide (MBA) as crosslinking agent and ammonium persulfate (APS) as initiator on the modified ATP–Fe3O4substrate. The optimum reaction condition was examined in detail. The results indicated that the prepared composite resin combined characteristics of stronger magnetism and higher oil absorbency. The resultant resin had high oil absorbency and the highest absorbencies respectively reaches 23.8, 25, 30.0, 32.6g.g for xylene, toluene, carbon tetrachloride and chloroform, which were higher than some oil absorptive materials previously reported. At the same time, it could easily be recovered and reused too. Kinetic investigation proved that the oil absorption obeyed the pseudo-first-order kinetic model and intraparticle diffusion model.
