Abstract: Molecularly imprinted polymeric membranes were prepared from cellulose acetate (CA), of which acetyl content was 40%, by applying the alternative molecular imprinting technique. The Z-D-Glu imprinted polymeric membranes thus obtained recognized D-Glu in preference to L-Glu from racemic Glu mixtures and vice versa. The affinity constants between Glu and the chiral recognition site for two binds of membranes were determined to be 3.1 x 10(3) mol(-1) dm(3) from the adsorption isotherm of D-Glu or L-Glu in the molecularly imprinted CA membranes. Enantioselective electrodialysis was attained with the present membranes reflecting their adsorption selectivity. D-Glu was preferentially permeated through the Z-D-Glu imprinted CA membrane, whereas L-Glu was permeated through the Z-L-Glu imprinted CA membrane. The present study suggests that the molecularly imprinted CA membranes are applicable to the optical resolution of racemic amino acids. (C) 1999 John Wiley & Sons, Inc
