摘要
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.
