Abstract: With chitosan as the functional matrix(FMx) and L-Proline(L-Pro) as the template molecule,(molecularly) imprinting polymer with both the spatial configuration and bonding sites matching to L-Proline was synthesised by means of the molecularly imprinting technology in water.The polymer product was characterized by IR,SEM and TG.Furthermore,the mechanism was explored preliminarily.The effects of pH,the amount of cross-linking agent and reaction time were studied.The optimum conditions were: pH=10.7,composite 1.0 g,cross-linking agent 8 mL,18 h at ambient temperature.The experimental results show that L-Pro-MIP has a superior selective adsorption capacity and efficient chiral separation of L-Proline in water phase,the(resolution) factor is 4.67.
