Preparation of new photo-crosslinked β-cyclodextrin polymer beads
Photo-crosslinkable groups were introduced to β-cyclodextrin (β-CyD) by the reaction of β-cyclodextrins with isophorone diisocyanate and 2-hydroxyethyl acrylate to produce polysubstituted photo-crosslinkable β-CyD (PSβCyD). To yield PSβCyD of a spherical shape, a suspension consisting of PSβCyD and...

Summary: | Photo-crosslinkable groups were introduced to β-cyclodextrin (β-CyD) by the reaction of β-cyclodextrins with isophorone diisocyanate and 2-hydroxyethyl acrylate to produce polysubstituted photo-crosslinkable β-CyD (PSβCyD). To yield PSβCyD of a spherical shape, a suspension consisting of PSβCyD and aqueous sodium alginate solution was added dropwise into an aqueous calcium chloride solution. Then, the PSβCyD macromonomer was photo-crosslinked with ultraviolet radiation to obtain β-CyD polymer beads. The physical properties of the highest quality polymer beads prepared were as follows: diameter (φ) 2.7 mm and compressive strength 6.5 MPa that showed 69% separation efficiency of phenol from the raw industrial 8.9 wt% phenolic waste water.
