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.

Abstract: An eco-friendly high-swelling superabsorbent composite CMC-g-poly(acrylic acid - 2-acrylamido-2-methylpropane sulfonic acid)/Attapulgite based on carboxymethyl cellulose (CMC) and inorganic clay Attapulgite (ATP) was prepared via a grafting copolymerization of acrylic acid (AA) and 2-acrylamido-2-methylpropanesulfonic acid (AMPS), using with N, N-methylenebisacrylamide (MBA) as a cross-linking agent, ammonium persulfate (APS) as an initiator and polyethylene glycol(PEG) as a phase transfer catalyst. The effects of polymerization conditions on the swelling ability of the superabsorbent composite were investigated. The results indicated that the prepared superabsorbent had high water absorbency. Saturated water absorbencies of the superabsorbent reached (864 g.g-1) for distilled water and (72 g.g-1) for 0.9 wt% NaCl aqueous solution respectively. The water absorbency of the composites was dependent on the pH of external solutions and used saline solutions.
