摘要：

The electrochemical behavior of tartaric acid at the CuGeO3 nanowire modified glassy carbon electrode has been investigated by cyclic voltammetry (CV). The results show that two pairs of semireversible electrochemical peaks are observed and can be assigned to the process of oxidation-reduction and adsorption-desorption of tartaric acid at the modified glassy carbon electrode, respectively. The intensity of the CV peaks increases linearly with the increase of the content of tartaric acid in the range of 0.01-5 mM and scan rate ranging from 25-200 mV s(-1). CuGeO3 nanowire modified glassy carbon electrode exhibits good detection ability for tartaric acid in neutral solution with the detection limit of 8.9 and 7.7 mu M for cvp1 and cvp2, respectively, at a signal-to-noise ratio of 3. The CuGeO3 nanowire modified glassy carbon electrode has good reproducibility and stability.
