The molecularly imprinted microspheres(MIMs-IL) were synthesized with hydroquinone as template molecules, α-acrylic acid as functional monomer and ethylene glycol dimethacrylate as cross-linker by suspension polymerization in two-phase system of ionic liquidbased aqueous. The MIMs-IL was characterized by FTIR and its selective recognition was evaluated by adsorption experiments. [Bmim]PF6 was selected from three different types of IL. Compared with that of the molecularly imprinted microspheres(MIMs-Or) prepared in twophase system of chloroformaqueous, the yield of MIMs-IL, 70.8% is obviously higher than that of MIMs-Or, 48.7%. The recognition adsorption of MIMs-IL for hydroquinone in water solution is higher than that of MIMs-Or. Moreover, the results of thermodynamics and kinetics of the recognition adsorption of MIMs-IL show that the saturation adsorption amount was achieved in 12 h, and MIMs-IL displayed a 2.67-fold increase in adsorption amount for 0.50 g/L hydroquinone water solution compared to its none molecularly imprinted microspheres(nMIMs-IL).
