摘要：
A molecularly imprinted microsphere (MIPs) was prepared successfully via surface-initiated reversible addition-fragmentation chain transfer (RAFT) polymerization. Characterization of the obtained MIPs was achieved by FT-IR and TGA. The isothermal adsorption and chiral separation experiments of MIPs on L-Carnitine were investigated. Compared with non-imprinted microsphere (NMIPs) adsorbent, MIPs showed faster adsorption rate and stronger adsorption capacity for L-Carnitine. Equilibrium experimental data of MIPs fitted the Langmuir isotherm better. Furthermore, the MIPs also exhibited enantioselectivity for L-Carnitine through the resolution experiment.
