该文用“嫁接”的方法将β-环糊精(β-CD)修饰在乙烷桥键有序介孔有机硅材料(PMO)上,并以同样的方法合成了β-CD修饰的介孔材料SBA-15作为对比材料。通过傅里叶变换红外光谱(FTIR)、高分辨透射电镜(HRTEM)、X射线粉末衍射(XRD)、氮气吸附以及热分析(TGA)对修饰前后的PMO材料进行表征。考察了修饰前后PMO材料对于水中污染物苯胺和对苯二酚的吸附性能,由结果可知,β-CD修饰的乙烷桥键有序介孔有机硅材料(PMO-CD)对于苯胺的吸附量为1.54 mg/g,相对于PMO材料而言,β-CD的修饰使其吸附能力被极大地抑制,而其对于对苯二酚的吸附量为12.94 mg/g,吸附性能得到了很大提高。因此,PMO-CD在处理水中污染物领域具有潜在的应用价值。
In this paper, β-cyclodextrin (β-CD) was modified on ethane bridging ordered mesoporous silica (PMO) by the method of “grafting” Mesoporous material SBA-15 as a comparative material. The modified PMO materials were characterized by FTIR, HRTEM, XRD, nitrogen adsorption and thermal analysis (TGA). The adsorption properties of PMO on aniline and hydroquinone in water were investigated. The results showed that the adsorbed amount of aniline on β-CD modified ethane-bridged ordered mesoporous silica (PMO-CD) Was 1.54 mg / g. Compared with PMO, the adsorption of β-CD was greatly inhibited, while the adsorption capacity of hydroquinone to hydroquinone was 12.94 mg / g and the adsorption performance was greatly improved . Therefore, PMO-CD has potential applications in the treatment of pollutants in water.
