Abstract: Microwave irradiation was firstly attempted to prepare molecularly imprinted polymers ( MIPs monoliths, which were in situ prepared rapidly with methacrylic acid (MAA) as a functional monomer, ethylene glycol dimethacrylate (EDMA) as a cross-linking agent, toluene and isooctane as the porogenic solvents and AIBN as an initiator. The baseline separation of isomers of hydroxybenzoic acid was achieved on these monolithic columns with 4-HBA as the template, but not on the blank polymer. Furthermore, some neutral compounds could also be baseline-separated on the imprinted polymer columns in the modes of pressure-driven capillary electrochromatography and low-pressure driven capillary electrochromatography. It was shown that the monoliths were not only used as the molecularly imprinted polymers but also as the reverse phase chromatographic material
Template and target information: hydroxybenzoic acid, 4-hydoxybenzoic acid, 4-HBA
