    Synthesis of NanoSized Spherical β-Cyclodextrin Brushes and Their Application in Phenol Removal

    • 摘要: 采用光乳液聚合的方法成功制备了以聚苯乙烯为核的纳米球形环糊精聚合物刷,并用动态光散射、紫外可见分光光度法等方法研究了纳米球形环糊精刷的结构及其对苯酚的吸附。环糊精单体在聚苯乙烯核表面接枝聚合后,聚苯乙烯核的粒径明显增大,且粒径分布窄。环糊精通过包合作用既能在水中选择性地吸附苯酚又能在乙醇中脱附,因此制得的纳米球形环糊精刷可以用于选择性地回收废水中的苯酚。

       

      Abstract: Nanosized spherical βcyclodextrin (βCD) brushes were synthesized by photoemulsion polymerization using polystyrene (PS) as the core and modified cyclodextrin polymer as the shell. The adsorption amount of phenol and the size of βCD brush were determined by UVvisible spectrophotometry and dynamic light scattering (DLS), respectively. Nanosized spherical βCD brushes were with narrow size distribution and confirmed by monitoring the size increase of PS core. Since βCD can selectively form hostguest association with phenol, the obtained nanosized spherical βCD brushes should be an ideal candidate for removal of trace amount of phenols from wastewater.
