Synthesis of chitosan–gelatin molecularly imprinted membranes for extraction of l -tyrosine

CS-GEL- l -tyr MIMs were prepared in aqueous phase using CS and GEL as functional polymers. The effect of crosslinking agent, PEG concentration and imprinting molecular content were examined. The results indicated that the MIMs have special selectivity to template molecules l -tyrosine, can effectively separate l -tyrosine from other substances in the water phase and the permeability rate was 13.42%.
