A novel nickel hydroxide nanoparticles/poly-Eriochrome Black T modified glassy carbon electrode (Ni(OH)2NPs/PEBT-modified GCE) was easily fabricated and characterized using scanning electron microscopy and electroanalytical techniques. The electrogenerated PEBT-modified GCE was used to incorporate the Ni(II) ions before the electrochemical polarization in an alkaline medium. Such a platform exhibited excellent catalytic behavior toward glycerol (GLY) in an alkaline medium. The oxidation of GLY on the Ni(OH)2NPs/PEBT-modified GCE proceeds in a diffusion-controlled process. The experimental conditions for the Ni(OH)2NPs/PEBT-modified GCE were optimized. The sensor detected GLY in a wide linear range based on cyclic voltammetry and chronoamperometry from 0.1 to 10 mM and 5 to 500 µM, respectively. These methods achieved a limit of detection of 0.06 mM and 1.96 µM with the sensitivity values of 4.99 μA M−1 and 14.94 μA M−1, respectively. [ABSTRACT FROM AUTHOR] |
