摘　　要：Based on the molecular recognition ability of conductive polymer and the peculiar properties of carbon nanotubes,a novel single wall nanotubes(SWNTs)compound poly(4-aminopyridine)modified electrode(SWNTs/POAPE)is prepared at glass carbon electrode(GCE).The electrochemistry response of nitrophenol isomers is studied at the SWNTs/POAPE.The re-sult indicates that o-,m-and p-nitrophenol are separated entirely at the SWNTs/POAPE interface.The electrode present here can be easily used to determine nitrophenol isomers simultaneously with higher sensitivity.

关 键 词：carbon nanotube compound poly(4-aminopyridine) modified electrode NITROPHENOL ISOMER voltammetry.
