文摘

A green preparation method for d-Tryptophan imprinted composite membrane was proposed. Only water was used as solvent through whole preparation and permeation processes. CaCl2 was selected as crosslinking agent to replace conventional organic agents. High enantioseparation performance in 98% ee can be obtained under mild conditions. Reducing the presence of concentration polarization improves water flux and % ee.
