Abstract: The molecular imprinting polymeric microspheres (MIPs) of stignmasterol were prepared by suspension polymerization, with stignmasterol as the printing molecule, methyl methacrylate (MMA) and methacrylic acid (MAA) as the functional monomers, vinyl benzene (VB) as the cross-linker, CaCO3 and SDS as the dispersants, and Na2S2O8 as the initiator. The average diameter was below 100 μm and the size distribution was narrow. The experiment results showed that the optimal recipe was 3 g stig.:40 mL MMA or 30 mL MMA+10 mL MAA:15 mL VB:4 g CaCO3+2 g SDS. During the polymerization Na2S2O8 was added batchwise, and in the early period a high speed stirring was applied, and with the going of the polymerization, the stirring rate was reduced. With a separation factor of over 1.65 and an adsorption capacity of 1.28 mg/g, the prepared MIPs had a strong selective adsorption toward stigmasterol.
