Phenolics Separation by Molecularly Imprinted Monolithic CEC Column

Abstract

Capillary electrochromatography CEC has investigated as a technique for the separation of the following phenoliccompounds: phenol, o- and m-cresol, p-dichlorophenol and 2,6-dichlorophenol, p- and o-nitrophenol. We haveproposed novel CEC monolithic column for selective separation of phenolics by Methacrylamidoantipyrine, MAAP, asa new charge-transfer monomer via multiple interactions both hydrogen bonding and hydrophobic interactions and4-nitrophenol. We have combined molecular imprinting with the ability of methacryloyl based modification in CECcolumn between p-nitrophenol and MAAP to create CEC-monolith suitable for phenol, o- and m-cresol, pdichlorophenol and 2,6-dichlorophenol, p- and o-nitrophenol separation
