摘要

Abstract

A novel graphene oxide doped poly(hydroxymethylated-3

4-ethylenedioxythiophene) (PEDOT-MeOH/GO) composite film was synthesized and utilized as an efficient electrode material for simultaneous detection of rutin and ascorbic acid (AA). PEDOT-MeOH/GO films were synthesized on glassy carbon electrode (GCE) by a facile one-step electrochemical approach and were characterized by scanning electron microscopy

UV-Vis spectroscopy

FTIR spectra and electrochemical methods. Then the PEDOT-MeOH/GO/GCE was applied successfully in the simultaneous detection of rutin and AA. The results showed that the oxidation peak currents of rutin and AA obtained at the PEDOT-MeOH/GO/GCE were much higher than those at the traditional conducting polymer PEDOT/GO/GCE

PEDOT-MeOH/GCE

PEDOT/GCE and bare GCE. Under optimized conditions

the linear ranges for rutin and AA are 20 nmol/L−10 μmol/L and 8 μmol/L−1 mmol/L

respectively. The detection limit is 6 nmol/L for rutin and 2 μmol/L for AA (S/N = 3)

which are lower than those of the reported electrochemical sensors.
