Abstract:
Nanosized spherical βcyclodextrin (βCD) brushes were synthesized by photoemulsion polymerization using polystyrene (PS) as the core and modified cyclodextrin polymer as the shell. The adsorption amount of phenol and the size of βCD brush were determined by UVvisible spectrophotometry and dynamic light scattering (DLS), respectively. Nanosized spherical βCD brushes were with narrow size distribution and confirmed by monitoring the size increase of PS core. Since βCD can selectively form hostguest association with phenol, the obtained nanosized spherical βCD brushes should be an ideal candidate for removal of trace amount of phenols from wastewater.
