| Abstract: | Using the high selectivity of the polymer film and the catalytic properties of carbon nanotubes, Poly - MG/MWC- NTs/GCE was prepared by polymerizing of malachite green on the surface of multi-walled carbon nanotubes/glassy carbon electrode （MWCNTs/GCE）. The conditions of electrochemical polymerization of malachite green and the electrochemical properties of Poly - MG/MWCNTs/GCE were investigated. By Studying the electrochemical behavior of p-nitrophenol on Poly - MG/MWCNTs/GCE, a method of detecting p-nitrophenol was developed. According to the electrochemical response, Poly - MG/MWCNTs/GCE can be used as electrochemical sensor for detection and quantitative analysis of p-nitrophenol. |
