| Abstract: | Phenol oxidation in
aqueous solutions was carried out in a pH range of 7-12 using cyclic
votlammetry (CV) and differential pulse voltammetry (DPV) studies on a glassy
carbon electrode. Peak potentials are found to be distinct for each pH value. A
linear relationship is observed between the peak current and the concentration
ranging from micro- to milli-molar levels. The peak current is found to be
proportional to the concentration of phenol up to 5  M that allows determination
of unknown concentrations of phenol down to 5 M. Using DPV technique, the
phenol concentration is detected up to a concentration of 0.5 M. |
