A simple electrochemical method for the determination of cyanuric acid (CA) has been developed based on a CuGeO3 nanowire modified glassy carbon electrode. The dense CuGeO3 nanowire film can be formed on the surface of the glassy carbon electrode. The roles of scan rate, CA concentration, and electrolytes with different pH values on the electrochemical responses of CA have also been analyzed. The intensities of two anodic peaks vary linearly with the increase of the scan rate from 25 to 200 mVs−1. The intensity of the electrochemical CV peak increases with the increase of the acidity of the electrolytes. The two anodic peak currents are linear with the CA concentration in the range of 0.005–2 mM. The linear correlation coefficient is 0.984 and 0.980 for the cyclic voltammogram peaks (cvp) cvp1 and cvp2, respectively. The detection limit is 4.3 μM and 2.1 μM for cvp1 and cvp2, respectively. The proposed electrochemical method is convenient and effective sensing of CA.
