Patent Title: Method for purifying sulfanilamide drug by using molecularly imprinted polymer
Publication date: 2012
Publication number: CN102344527

Abstract: The present invention belongs to the technical field of bioengineering, and relates to a method for purifying sulfanilamide by using a molecularly imprinted polymer of a sulfanilamide drug. The method comprises the following steps: (1) mixing and dissolving template molecules of a sulfanilamide drug mixture, a functional monomer of methacrylic acid and a cross-linking agent of ethylene glycol dimethacrylate in a pore forming agent (a ratio of methanol to acetonitrile is 2:3); adding an initiator, and sealing; (2) crushing the synthesized polymer, removing fine particles, removing the template molecules through extraction; (3) drying the template molecule-removed polymer overnight at a temperature of 60 DEG C to obtain the molecularly imprinted polymer of the sulfanilamide; (4) filling the molecularly imprinted polymer into a solid phase extraction column tube; (5) activating the solid phase extraction column, adding an animal tissue extraction solution or a water sample, wherein the animal tissue extraction solution is dissolved in 40% methanol; then leaching the solid phase extraction column to elute and purify the sulfanilamide. The method provided by the present invention has advantages of high selectivity, high specificity and adverse environment resistance, and has broad application potential.
