通过氯甲基化的苯乙烯一二乙烯苯共聚物的后交联及单宁酸的化学修饰反应制备了单宁酸修饰的超高交联吸附树脂（TAMR），通过红外光谱、元素分析、扫描电镜和比表面孔径分析对TAMR树脂的结构特征和表面参数及形貌进行表征．通过等温吸附实验和吸附动力学实验研究了苯酚、对硝基苯酚和对氯苯酚在TAMR树脂上的吸附性能和吸附机理．结果表明，TAMR树脂具有较高的比表面积（780．1m2／g）和较丰富的微孔（482．3m2／g），树脂表面修饰了较丰富的羟基．TAMR树脂对苯酚、对硝基苯酚和对氯苯酚均具有较好的吸附性能，288K时吸附量分别可达1．43、2．07和2．48mmol／g（c0为500mg／L）．3种酚类化合物在TAMR树脂上的吸附为典型的物理吸附，其吸附焓变和熵变均为负值．当酚类化合物以分子形态存在时，有利于其被TAMR树脂吸附．Langmuir和Freundlich方程均能较好地拟合酚类化合物在TAMR树脂上的吸附等温线．吸附动力学过程符合准一级动力学方程，颗粒内扩散过程是TAMR树脂吸附这3种酚的吸附速率的主要控制步骤．

英文摘要：

A new hyper-crosslinked resin TAMR was prepared by post-crosslinking of chloromethyl low crosslinking macroporous polystyrene and subsequent chemically modifying with tannic acid. The physicochemieal structure of TAMR was elaborately characterized using Fourier transform infrared spectroscopy （FTIR） , elemental analysis （EA）, scanning electron microscopy （SEM） and was further morphologically characterized using BET and BJH methods. The specific surface area of TAMR was about 780. 1 m2/g and the micropore specific surface area was about 482. 3 m2/g. The content of phenolic hydroxyl group （--OH） in TAMR was about 1.87 mmol/g. The adsorption performances and mechanism of TAMR towards phenolic compounds （phenol, p-nitrophenol and p-ehlorophenol） were studied through the isotherm adsorption and batch kinetics experiments. The isotherm adsorption results showed that TAMR had good adsorption capabilities to phenol, p-nitrophenol and p-chlorophenol because of the high specific surface area and relatively abundant micropore distribution, as well as the phenolic hydroxyl groups on the surface of TAMR. The adsorption capacities of phenol, p-nitrophenol and p-chlorophenol were 1.43, 2.07 and 2.48 mmol/g at 288 K （co was 500 mg/L） , respectively. The adsorption of phenolic compounds on TAMR was an exothermie typical physical adsorption process which was in accordance with both Langmuir and Freundlich isotherm equations. The phenolic compounds adsorbed onto TAMR kept constant under acidic pH conditions and descended dramatically when the solution pH turned to alkaline, especially when pH was over their pKa value. The molecular form of phenolic compounds was favorable for the adsorption. Quasi-first kinetic adsorption equation could describe the adsorption dynamics behavior perfectly, which meant inner diffusion of the particles was the major controlling step of adsorption process. The perfect regeneration adsorption performance meant that TAMR could be applied widely for treating of phenolic compounds w
