Abstract: The invention relates to a preparation method and application of a molecularly imprinted polymer of sulfadiazine for controlled catalytic degradation, belonging to the technical field of material preparation and pollution control of water environments. The molecularly imprinted polymer of sulfadiazine for controlled catalytic degradation is prepared according to the steps of preparation of a substrate material of a molecularly imprinted controlled catalytic material by loading catalytic inorganic nanoparticles on a surface of a silica nanosphere, and coating of a layer of imprinted polymer on the surface of the silica nanospher by a controlled polymerization technology. When observed through a transmission electron microscope, the catalytic material has a uniform microstructure and good dispersibility. The catalytic degradation capability of the catalyst is evaluated by a static catalytic degradation experiment. Experimental results show that the catalyst has certain selective catalytic degradation capability for sulfadiazine and good regeneration performance and can be used in certain potential applications.
