A copolymer, poly(aniline-co-m-aminophenol), was synthesized by copolymerization of aniline and m-aminophenol in the presence of l-glutamic acid (l-Glu) as template molecules. The copolymer was filled into a porous ceramic column as the conductive stationary phase. Enantioselective recognition of Glu enantiomers was achieved on this special electrode column by applying different potentials on copolymers in the ceramic column. l-Glu anions were ejected from the ceramic column after electrochemical reduction due to the reversible redox of the copolymer while complementary cavities were left. Then a positive potential was applied to the molecularly imprinted poly(aniline-co-m-aminophenol) for re-binging Glu enantiomers in the mobile phase. The results showed good enantioselectivity.
Glutamic acid enantiomers can be recognized successfully with the novel electrode column packed with the imprinted poly(aniline-co-m-aminophenol) by potential-induced technique.Figure optionsDownload as PowerPoint slideHighlights
► Poly(aniline-co-m-aminophenol) is used as a stationary phase in the electrode column.
► The usable pH region of the electrode column is broadened significantly.
► Glutamic acid enantiomers can be recognized by using potential-induced technique.
