Abstract: In this work, a simple and effective method for chiral membrane preparation is demonstrated, involving electrostatic interaction between negatively charged sulfobutylether-β-cyclodextrin (SBE-β-CD) as a chiral selector and a commercially available anionexchange membrane.The modified home-made chiral membrane was tested in diffusion cells to characterize its enantioselectivity towards D,L–Tryptophan. We demonstrated in our work that L–Tryptophan is preferentially absorbed into the membrane, while D–Tryptophan\nis transported through the membrane with enantiomeric excess exceeding 80%. To increase the permeation rate of the membrane, thinner ion-exchange membrane substrate with higher degree of swelling is proposed.\n
