Abstract
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.
