Description
Summary:•The CuGeO3 nanowires can be used for the electrochemical detection of phenyl acetic acid.•The detection limit is 9.1μM with a linear range of 0.01–2mM.•The CuGeO3 nanowire modified glassy carbon electrode exhibits good reproducibility, stability and sensibility. The phenyl acetic acid (PAA) has been determined by cyclic voltammetry with electrochemical detection using CuGeO3 nanowires as the glassy carbon electrode (GCE) modified materials. The electrochemical behaviors of the PAA at the CuGeO3 nanowire modified GCE in neutral solution show that two pairs of electrochemical CV peaks are observed. Two anodic CV peaks are located at 0.31V and −0.02V for cv peak 1 and cv peak 2, respectively. The intensities of two anodic peaks vary linearly with the increase of the PAA concentrations from 0.01 to 2mM. The detection limit is 82.1μM and 9.1μM for cv peak 1 and cv peak 2, respectively. The CuGeO3 nanowire modified GCE exhibits good reproducibility, stability and sensibility.
