摘要

Glyoxalic acid was determined by electrochemical cyclic voltammetry method using copper germanate (CuGeO_(3)) nanowires as the modified glassy carbon electrode (GCE) materials. The CuGeO_(3) nanowire modified GCE exhibited good detection performance for glyoxalic acid in neutral solution. The intensities of two anodic peaks vary linearly with the increase of the scan rate from 25 to 200 mVs~(?1) and glyoxalic acid concentration from 0.001 to 2 mM. The detection limit was 8.5 μM and 0.78 μM for cvp1 and cvp2 with the correlation coefficient of 0.991 and 0.998, respectively. The CuGeO_(3) nanowire modified GCE exhibited good reproducibility and stability.
