Recent Developments in Molecularly Imprinted Polymers for Selective Recognition of Deleterious Organic Pollutants at Trace Concentration in Aqueous Media

Molecularly imprinted polymers （MIPs） are synthetic polymers possessing specific cavities designed for a target molecule. By a principle of molecular recognition, the molecularly imprinted techniques （MITs） can be used as selective tools such as liquid chromatography, solid-phase extraction （SPE） and biosensors in determination of various compounds. Based on the discussion that the recognition ability to organic molecules can be strengthened by β-cyclodextrin in design and syn- thesis of MIPs, application of MIPs in determination of deleterious organic pollutants at trace concentration in aqueous media is described with a special emphasis on MIPs as selective SPE sorbent for the selective extraction of target analyses from complex matrices.
