Synthesis of Molecularly Imprinted Copolymer and its Application as a SPE Sorbent for Preconcentration of Metoprolol and Vitamin B₆ from Water

Abstract

Molecularly imprinted polymer – copolymer of methacrylic acid (MAA) and ethyleneglycol dimethacrylate (EGDMA) with imprints of metoprolol molecules was synthesized. To optimize conditions of its synthesis, the following parameters were studied: influence of molar ratio of the monomer (MAA) to the crosslinker (EGDMA), chemical nature of porogen, and its volume ratio to monomers mixture on the porous structure of the final copolymer.

In order to study the sorption properties of this polymeric material, the recoveries and breakthrough volume of metoprolol and vitamin B₆ were determined. Their values are compared with those obtained for the MAA-EGDMA reference copolymer.
