摘要(Abstract)：

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?G的计算结果表明吸附过程是自发进行的。

关键词(KeyWords)： FDU-15;SBA-15;苯甲酸;吸附
