Abstract: By surface thermal-polymerization method, a molecularly imprinted composite membrane with polysulfone (PSF) basement membrane for L-dibenzoyl-L-tartaric acid(L-DBTA) was developed by using a template of L-DBTA with methyl methcrylate (MMA) as functional monomer and glgcol dimeth-yarylate (GDMA) as a cross-linker, and the pervaporation properties of this molecularly imprinted composite membrane for isopropanol (IPA)/water system were studied. The pervaporation results show that IPA (w = 0.50)/water solution can be completely separated by L-DBTA imprinted composite membrane, a maximum separation factor can reach 5690, flux is 551 g/(m2 / h) at IPA (w = 0.50)/water solution, 2400 and 1440 g/(m2 / h) for IPA (w = 0.20)/water solution, 82100 and 739 g/(m2 / h) for IPA (w = 0.95)/water solution
Template and target information: L-dibenzoyl-L-tartaric acid, L-DBTA
