Abstract: In the present study, cellulose, one of the most abundant natural polymers, was adopted as a membrane material for optical resolution. The membrane was prepared from cellulose, and it selectively transported l-glutamic acid (l-Glu) from racemic mixtures of Glu with a concentration gradient as the driving force. A molecularly imprinted cellulose membrane, which was constructed from cellulose and l-Glu, showed d-glutamic acid (d-Glu) permselectivity, which is thought to be due to a strong interaction between l-Glu and the molecularly imprinted cellulose membrane. The performance of both membranes was significantly dependent on LiCl, which was used to dissolve cellulose into an N,N-dimethylactamide (DMAc) solvent. The permselectivity increased with the LiCl concentration and asymptotically reached a maximum value at higher LiCl concentrations. The affinity constant of LiCl for the LiCl recognition sites in both membranes was 65 mol-1 dm3
