Molecular imprinting material for desulfurization and preparation method thereof

The invention belongs to a molecular imprinting material preparation technology and an application direction thereof, and relates to a preparation method for a molecular imprinting material for desulfurization. Specifically vinyl pyridine is adopted as a functional monomer, a benzothiophene sulfide is adopted as template molecule, and an appropriate cross-linking method is selected to prepare a molecular imprinting material capable of identifying and adsorbing sulfides. According to the method, the functional monomer, the template molecule and the cross-linking agent are subjected to a polymerization reaction, an elution method is adopted to remove the template molecules in the polymer, and the formed molecular imprinting material has multiple action sites matching with spaces of the benzothiophene sulfide. The molecular imprinting material of the present invention can effectively identify and remove the benzothiophene sulfide. The preparation method has characteristics of simple process, and easy enlarging a
