Patent Title: Dibutyl phthalate molecularly imprinted polymer (DBP-MIP) solid phase extraction column and preparation method and application thereof
Publication date: 2012
Publication number: CN102371084

Abstract: The invention provides a dibutyl phthalate molecularly imprinted polymer (DBP-MIP) solid phase extraction column and a preparation method and application method thereof, belonging to the technical field of analytical chemistry. The DBP-MIP is prepared by dissolving a template molecule DBP, a functional monomer methacrylic acid and a crosslinking agent ethylene glycol dimethacrylate into a porogen chloroform or acetonitrile, adding an initiator azobisisobutyronitrile, filling nitrogen to remove oxygen, carrying out initiated polymerization at 55-75 DEG C, and grinding, sieving and washing a polymer after completing reaction. The preparation method is characterized by weighing a certain amount of polymer and filling the polymer into a polypropylene column to prepare the solid phase extraction column. The prepared MIP solid phase extraction column can highly selectively separate and enrich DBP in samples such as environment, food, chemical products and the like and effectively remove matrix interference, and has great application values and market prospects.
