Abstract

40wt.% polyaniline/CuGeO₃ nanowires have been used as the glassy carbon electrode (GCE) modified materials for the electrochemical determination of cyanuric acid. The effect of scan rate, cyanuric acid concentration and electrolytes on the electrochemical behaviors of cyanuric acid has been analyzed. Polyaniline content on the electrochemical determination of cyanuric acid has also been discussed. The intensities of the cyclic voltammogram (CV) peaks vary linearly with the increase of the scan rate and cyanuric acid concentration. The detection limit is 1.9 µM and 1.1 µM for cvp1 and cvp2, respectively and linear range is 0.005-2 mM using 40wt.% polyaniline/CuGeO₃ nanowire modified GCE. The detection limit decreases with increasing the polyaniline content.

Keywords: Cyanuric acid, polyaniline/CuGeO₃ nanowires, electrochemical analysis and cyclic voltammetry method.
