【摘要】 采用高效液相色谱法研究了静电纺聚苯乙烯纳米纤维对水中苯系物有机污染物的吸附性能,探究了纳米纤维对苯、对氯苯、硝基苯的吸附容量随浓度和时间的变化规律.通过实验得到静电纺纳米纤维对苯、对氯苯、硝基苯的平衡吸附容量平均值分别为9.82,5.57和4.4mg.g-1,静态吸附4h后基本达到平衡.实验结果表明,静电纺聚苯乙烯纳米纤维能够较好地吸附苯类物质,并能多次重复利用,对水中较低浓度的苯类物质吸附是一种比较合适的吸附材料.更多还原

【Abstract】 The adsorption behavior of simple aromatic compounds (benzene,chlorobenzene and nitrobenzene ) in water on electrospun polystyrene nanofibers were investigated.The adsorption capacity of benzene,chlorobenzene,and nitrobenzene were 9.82,5.57 and 4.4 mg·g-1,respectively.The static adsorption equilibrium is accomplished within 4 h.The adsorption data of three compounds on the polystyrene nanofiber fit well with Freundlich isotherm.The experiment showed that the electrospun polymer nanofiber can be used to adsorb the aromatic compounds in water,and could be reused.It has the potential to be used as adsorption material for aromatic pollutants in water.更多还原
