Abstract: A hollow molecular imprinted polymer(H-MIP)was synthesized on silica as a sacrificed material by using 4-methyl dibenzothiophene(4-MDBT)as template,4-vinyl pyridine(4-VP)as function monomer.The sorbents were characterized by the Fourier transform infrared spectroscopy,nitrogen adsorption and scanning electron microscopy.The adsorption properties of the sorbents were investigated in the model oil.The results indicated that a molecular imprinted layer with porous structure was successfully synthesized on the surface of silica,and H-MIP not only had better surface characteristics but it also performed good specific recognition to 4MDBT.The adsorption process followed the pseudo-second-order kinetic model,and it was described well by Freundlich isotherm model.The adsorption thermodynamic parameters showed the adsorption was spontaneous endothermic process.The equilibrium adsorption amount reached 18.31498mg/g at the temperature of 328K,and the adsorption time was 3h.
