摘要

Molecularly imprinted polymeric membranes were prepared from cellulose acetate (CA), of which acetyl cotent 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 kinds of membranes were determined to be 3.1*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.
