Abstract

Abstract: Several amino acid chiral ionic liquids were introduced as functional monomers to prepare molecularly imprinted polymers for specific recognition of L‐phenylalanine. Among them, the imprinted polymers L‐Phe@MIPs based on [ViImC3][L‐Pro] showed the best selective recognition ability for L‐phenylalanine. A series of experiments such as dynamic adsorption, static adsorption, and competitive adsorption were conducted to investigate the specific recognition ability and adsorption capacity of the L‐Phe@MIPs. It is found that the adsorption efficiency to L‐phenylalanine on L‐Phe@MIPs was 3.11 times higher than that to D‐phenylalanine. All the results demonstrated that the L‐Phe@MIPs possessed good recognition and relatively high adsorption efficiency for L‐phenylalanine. Besides, the recovery of L‐phenylalanine was above 98%, and the L‐Phe@MIPs exhibited good reusability. Abstract :
