中文摘要：

采用软模板剂方法分别合成了具有二维六方（p6mm）高度有序结构的FDU-15介孔聚合物和SBA-15硅基介孔材料。通过XRD和氮气吸附．脱附等方法对介孔材料的介孔结构、比表面积及孔体积等进行了表征。分别考察了FDU-15和SBA-15对水溶液中苯甲酸的吸附行为。实验结果表明，FDU-15和SBA-15对水溶液中苯甲酸的吸附过程符合Freundlich吸附等温模型。通过等温吸附实验和热力学参数的计算，研究了FDU-15对苯甲酸的吸附性能及吸附机理，结果表明，FDU-15对苯甲酸具有良好的吸附效果，吸附量随着温度的升高而增大，FDU-15对苯甲酸的吸附是吸热过程。热力学参数AG的计算结果表明吸附过程是自发进行的。

英文摘要：

The FDU-15 mesopolymer and the SBA-15 mesoporous material with well-ordered two-dimensional hexagonal （p6mm） structure were synthesized by a soft-template method, respectively. The pore structure, specific surface area and pore volume of FDU-15 and SBA-15 mesoporous materials were characterized by the X-ray diffraction （XRD） and nitrogen adsorption-desorption techniques. The adsorption behaviors of benzoic acid on FDU-15 and SBA-15 were investigated. The equilibrium adsorption data for benzoic acid was analyzed by Freundlich adsorption isotherm model. The adsorption properties and mechanism of benzoic acid on FDU-15 were further studied based on isothermal adsorption experiments and the adsorption thermodynamic parameters. The results showed that FDU-15 had good adsorption capability of benzoic acid. The increase ~3f temperature results in the increase of adsorption capacity, which indicated that the adsorption of benzoic acid on FDU-15 was an endothermic process. The negative value of Gibbs free energy change （AG） indicated that the adsorption process was spontaneous.
