Abstract: Oleanolic acid (OA) as template molecules, polyamide-6 (PA6) as basement membrane and poly(styrene-co-maleic acid) (PSMA) were used to prepare PA6/PSMA-OA molecularly imprinted composite membranes (PA6/PSMA-OA MICMs) by phase inversion method. The template molecules (OA), polymers [poly(styrene-co-maleic anhydride) (PSMAH), PSMA], MICMs imprinting OA and MICMs after elution were all characterized by Fourier Transform Infrared Spectroscopy (FTIR). And the optimum condition was obtained as follows, polymer concentration 14%, temperature of distilled water 15 °C and dipping time 20 h, respectively. After template molecules being removed, the MICMs had effective selectivity hydrogen bonding to separately bind in the binary components to the template molecules-OA.
