Indomethacin molecular imprinted polymer preparation, characterization of application

摘要

In order to indomethacin (IDM) for imprinting molecular, acrylamide (AA) as functional monomer, ethylene glycol dimethacrylate (EGDMA two) as crosslinking agent, respectively by photopolymerization and thermal polymerization of two methods of aqueous solution polymerization, suspension polymerization preparation of molecularly imprinted polymer. The polymer adsorption experiments show that the use of light-polymerized specificity is strong; light initiated polymer used for sample determination and calibration experiments, results in tap water and river water samples in Enshi Qingjiang indomethacin recoveries were 84.3% and 87.1%, were higher than 80%. Tap water and the relative standard deviation (n = 3) were 3.96%, 14.2%, that can be used for the separation and enrichment of indomethacin in water samples.
