摘要

Herein, poly(3,4-ethylenedioxythiophene) (PEDOT) films doped with transition metals were electrochemically synthesized. Transition metal ions-EDTA (M-EDTA, M = Cu2+, Mn2+, Fe3+, Co2+, Ni2+) complexes served as dopants. Rutin as model molecular was utilized to investigate its electrochemical responses at PEDOT/M-EDTA modified electrodes. It was found the PEDOT/Co2+- EDTA exhibited better electrocatalytic activity toward rutin oxidation than other PEDOT/M-EDTA modified electrodes. Thus, PEDOT/Co2+-EDTA film-based electrochemical sensor was used to detect rutin. Low detection limit (1.67 nM), good reproducibility and wide linear range (5 nM-100 μM) were obtained. The sensor was employed for the determination of rutin in buckwheat tea. These results suggest that PEDOT/Co2+-EDTA could be utilized as a promising sensing platform for rutin detection.
