Abstract_Chinese:以苯乙烯为单体, 二乙烯基苯为交联剂, 以线性聚苯乙烯为致孔剂, 通过悬浮聚合制备了含有少层石墨烯的多孔聚苯乙烯微球．通过扫描电镜、X射线衍射、差热分析等手段对微球的结构进行了表征．采用紫外-可见光分光光度法研究了微球对苯酚、喹啉及吲哚等有机污染物的吸附行为．结果表明：聚苯乙烯/石墨烯微球具有多孔的微观结构; 该聚合物微球对苯酚基本无吸附效果, 但对吲哚及喹啉有较好吸附性能, 并且吸附行为均符合准二级动力学吸附模型, 对喹啉、吲哚的饱和吸附量分别为1.18 mg/g和0.79 mg/g; 该聚合物微球能够至少20次重复吸附-解吸循环, 具有良好再生性能．该聚苯乙烯/石墨烯复合微球有望在有机废水处理领域获得应用．
Abstract_English:The porous polystyrene microspheres with a few-layer graphene were prepared by suspension polymerization of styrene(monomer)with divinylbenzene(crosslinking agent)and linear polystyrene(pore-forming agent). These microspheres were characterized by means of scanning electron microscopy，X-ray diffraction and thermo-gravimetric analysis. The adsorptions of phenol，quinoline and indole were measured by UV-visible spectrometer. Results show that the polystyrene/graphene microspheres with porous structure hardly adsorbed phenol but sufficiently adsorbed quinoline and indole. The adsorption of quinoline and indole can be both well described by a pseudo-second-order kinetics adsorption model，and the adsorption capacities were 1.18 mg/g and 0.79 mg/g，respectively. These microspheres can be regenerated in 20 adsorption-desorption cycles. The polystyrene/graphene microspheres provide a new material for organic wastewater treatment.
