抜粋

Transport behavior of several aromatic compounds through a poly(vinyl chloride)membrane and poly(vinyl alcohol)‐poly(ethylenimine) composite membranes was studied in the presence of cyclodextrin in the aqueous solution. o‐Isomers of nitrophenol, nitroaniline, and iodophenol were effectively separated from their mixture of regio isomers based on the preferential complexation between cyclodextrin and the m‐ and p‐isomers over the o‐isomers. Pumping of p‐nitroaniline across the membrane was also observed by addition of cyclodextrin. The results were explained as a consequence of the selective complex formation between cyclodexarin and substrate and the low membrane permeability of the complexes.
