摘要：
a-Cyclodextrin (alpha-CD) was immobilized by the radiation-induced gelation of poly(vinyl,alcohol) (PVA). An aqueous solution of 4-nitrophenol (4-Np) was added upon the PVA hydrogel containing alpha-CD in a quartz cell. Absorption spectra of the hydrogel phase have demonstrated that 4-Np permeates into the hydrogel and is included by alpha-CD. When pure toluene was added upon the hydrogel, the rate of the permeation of toluene was affected by the inclusion complexation with alpha-CD. (C) 2003 Elsevier Ltd. All rights reserved.
