| Abstract: | A poly(4-aminopyridine) (POAP) modified electrode was prepared atglassy carbon electrode. The electrochemical behavior of dicynonum (DIC) using this modified electrode was studied. the POAP electrode showed excellent electrocatalytic activity for the oxidation of dicynonum. A couple of sensitive and reversible redox peaks were obtained from the cyclic voltammograms. The relationship between oxidation peak current and the concentration of DIC was linear in the range of 4.0×10－8～1.0×10－3 mol/L under the optimum conditions. The detection limit has been estimated as 7.6×10－10 mol/L with 5 min open circuit accumulation. The POAP electrode showed excellent reproducibility, sensitivity and stability for the determination of DIC. |
