Patent Title: Method for preparing apiolin molecularly imprinted polymer
Publication date: 2010
Publication number: CN101665551

Abstract: The invention relates to a method for preparing an apiolin molecularly imprinted polymer, comprising the following steps: dissolving apiolin and a functional monomer of 1 mol fraction of template molecule according to the mole ratio of 1:4-1:10 in 40 parts by volume of butylene oxide of a pore-foaming agent; vibrating away from light at constant temperature for 6h; then adding ethylene dimethacrylate as a crosslinking agent, the amount of which is 4-7 times of that of the monomer, and azodiisobutyronitrile as an initiating agent, the quality of which is 1 percent of that of the monomer and thecrosslinking agent, and completely mixing; sealing after N2 is introduced to remove oxygen; carrying out thermal-initiated polymerization at the temperature of 40-60 DEG C for 24-48h, and then obtaining a rod-shaped solid polymer; rubbing and then sieving the polymer; utilizing a methanol/acetic acid (v/v=6:4) eluent to elute so as to remove the template molecule; putting in a vacuum drying cabinet and then drying until constant weight, and then obtaining the apiolin molecularly imprinted polymer. The apiolin molecularly imprinted polymer prepared by the method has specific identification ability and selective adsorption performance on apiolin. Compared with common sorbents, the polymer has the advantages of accuracy, rapidness and sensitivity. Moreover, the polymer has high percent recovery, good repeatability and long service life, thereby having wide application prospects.
