molecularly imprinted polymers(MIP) for Dibutyl phthalate(DBP) was synthesized on the surface of silica gel with DBP as template molecule, acrylic acid as functional monomer and vinyltrimethoxysilane as grafting agent. The intermolecular interaction between acrylic acid and DBP was confirmed by ultraviolet spectroscopy(UV) , the surface morphology of the MIP was characterized by scanning electron microscope (SEM) and the structure of polymers was analyzed by fourier transform infrared spectroscopy (FTIR). The binding properties of the MIP were evaluated by equilibrium adsorption experiment method. The scatchard plot suggested that the template-polymer system had two site of adsorption behavior with the dissociation constant(Kd) of 0.0284 mmol L-1, 0.675 mmol L-1 and the max adsorption capacity(Qmax) of 4.035 祄ol g-1, 30.507 祄ol g-1 for the higher affinity site and lower affinity site, respectively. In addition, the selectivity factor of DBP towards dimethyl phthalate(DMP) and bis(methoxyethyl) phthalate (DMOP) was 2.04 and 1.57, respectively. Indicating good recogntion characteristic to DBP.
