Abstract: A molecularly imprinted polymer (MIP) for thiophene was prepared by a molecular imprinting technique. Influential factors on adsorption capability and recognition performance of MIP for thiophene, such as functional monomer, crosslinker types, solvent, molar ratio of template molecule to functional monomer, were investigated. The results showed that the imprinted polymers, prepared at 60 °C by using α-methylacrylic acid as functional monomer, ethylene glycol dimethacrylate as crosslinker, chloroform as solvent and 2,2'-azobisisobutyronitrile as the initiator, exhibited good adsorption capacity and recognition performance for thiophene. This study may provide a theoretical basis for deep desulfurization of gasoline to remove sulfur-contained thiophenic compounds.
