Description
Summary:In the oil–water separation, the difficulty to recover and low hydrophobicity are key limitation factors for practical applications. In this paper, we design Cobalt ferrite hybrid Polystyrene divinylbenzene microspheres (CoFe 2 O 4 /SDB), which were conducted through in situ suspension copolymerization. The CoFe 2 O 4 is prepared by low heat solid phase sol-gel method. It had been found that the CoFe 2 O 4 /SDB have a spherical structure, good adsorption behavior, highly hydrophobicity and even superhydrophobicity. The adsorption capacity of CoFe 2 O 4 /SDB composites could absorb kerosene up to 6 times of its own weight. Interestingly, kerosene can be easily separated from the surface of CoFe 2 O 4 /SDB particles with ultrasonic operation. CoFe 2 O 4 /SDB particles can still maintain good hydrophobicity and adsorption capacity of kerosene after 11 cycles after drying. With in situ polymerization of St:DVB and CoFe 2 O 4 , CoFe 2 O 4 /SDB as a promising absorbent of kerosene which has great potential in application of oil–water separation.
