Cyclic voltammetry of phenol

The possibility of phenol determination by cyclic voltammetry ( CVA ) on electrochemically modified glassy-carbon electrodes ( GCE ) was studied. The effect of the rate of linear potential sweep on the sensitivity of phenol determination was investigated. The adsorption nature of the analytical signal of phenol was revealed. The formation of the hydroquinone-quinone couple by the electrochemical oxidation of phenol was proved by CVA.
