英文摘要: Abstract(#br)Superhydrophobic materials have an excellent performance in oil adsorption. In this study, a novel magnetic polydivinylbenzene (PDVB) nanofiber was synthesized by the method of cation polymerization to adsorb oil from water. The magnetic PDVB was hollow nanofiber with Fe 3 O 4 nanoparticles embedded in its structure. The synthesis condition was optimized that the ratio of divinylbenzene (DVB) to boron fluoride ethyl ether (BFEE) was 10:1 ( v / v ), and the Fe 3 O 4 dosage was 0.175 g/g of DVB. The material showed an excellent oil adsorption performance in wastewater, and the oil concentration could be reduced from 2000 to 92.2 mg/L within 5 min. The magnetic PDVB had relatively high adsorption capacity (12 g/g) for oil, which could be attributed to its super hydrophobicity...
