Molecularly imprinted polymeric membranes were prepared from amorphous poly(hexamethylene terephthalamide/isophthalamide). Membranes imprinted bq Z-D-Glu recognize the D-isomer, of which absolute configuration is the same as that of the print molecule, in preference to the corresponding L-isomer, and vice versa. The amino acid preferentially. adsorbed by the membrane was also selectively permeated by electrodialysis. An optimum separation factor of 2.0 was reached at the applied potential difference of 2.0 V.
