苯酚在介孔材料上的吸附性能的研究

Study on the Adsorption of Phenol on the Mesoporous Materials

采用软模板剂方法分别合成了二维六方(p6mm)结构的有序FDU-15介孔聚合物和硅基介孔材料SBA-15。通过XRD、SEM、氮气吸脱附等测试手段对材料的结构、孔笼等进行了表征。考察了FDU-15和SBA-15吸附水溶液中苯酚的吸附行为,研究了不同温度下水溶液中苯酚的静态吸附,随着温度的升高吸附量增大。Langmuir和Freundlich方程能够对苯酚在FDU-15上的吸附性能进行很好的拟合。

Mesopolymer material FDU-15 and silica-based mesoporous material SBA-15 with both hexagonal mesostructure（p6mm space group） were prepared by soft-template method.Various techniques such as XRD,SEM,N2 adsorption-desorption,etc.were adopted to characterize their structures and porosity.The adsorption property of phenol in water onto the FDU-15 and SBA-15 was discussed.Studies on the adsorption kinetics of phenol by the FDU-15 were carried out through static experiments at different temperature,the capacity of the adsorption increased with temperature.Adsorption of phenol onto the FDU-15 was successfully described by Langmuir and Freundlich isotherm equation models.
