中文摘要：

用二氯乙烷为溶剂,用FeCl3为催化剂,使氯球和对乙酰氨基酚发生Friedel-Crafts反应制得了对乙酰氨基酚修饰的后交联树脂,对其结构进行了表征,研究乙酰氨基和酚羟基二类氢键作用位点修饰的后交联树脂对双酚A的吸附性能.结果表明,红外光谱显示对乙酰氨基酚已被成功地修饰在后交联树脂上.对乙酰氨基酚修饰的后交联树脂与氯球相比,BET比表面积、孔容明显增大,孔径明显变小.对乙酰氨基酚修饰的后交联树脂对双酚A的吸附量明显高于75%活性炭的聚砜微球对双酚A的吸附量.对乙酰氨基酚修饰的后交联树脂对双酚A的吸附为放热、自发的过程;树脂可以用100%酒精解吸,解吸率为99.92%;吸附动力学数据符合一级吸附速率方程,颗粒内扩散是吸附速率的主要控制步骤,吸附速率同时还受液膜扩散的影响.

英文摘要：

The adsorption performances for bisphenol A onto the hypercrosslinked resin with two kinds of the hydrogen bond site of acetamino group and hydroxyl group was studied.The hypercrosslinked resin modified with acetaminophen was synthesized with chloromethylated polystyrene and acetaminophen by Friedel-Crafts reaction.Dichloroethane was used as solvent and ferric chloride was used as catalyst.The structures of the hypercrosslinked resin were characterized.The acetaminophen was successfully modified into the hypercrosslinked resin that revealed by the Infrared spectra.Comparison with the chloromethylated polystyrene,the BET surface area and pore volume of the hypercrosslinked resin modified with acetaminophen was increased significantly,the pore size was much smaller.The adsorption capacity of bisphenol A onto the hypercrosslinked resin was obviously superior to polysulphone micro-ball embedded with 75% activated carbon.Heat was discharged during the adsorption and the adsorption occurred automatically.The resin could be desorbed with 100% ethanol.The desorption rate of 100% ethanol was up to 99.92%.The adsorption kinetic date of bisphenol A was fitted to the first order rate equation.The intrapartical diffusion of bisphenol A was the main rate-controlling step.Adsorption rate was also affected by the impact of film diffusion.
