Development of phenol measurement techniques by voltammetry in waste and regulatory effluents

The opportunity to obtain analytical signal of phenol on glassy carbon electrode and the background of 0.003 M solution of NaOH is discussed. In these conditions, the peak of phenol was observed at the potential of 0.52 V during the investigation of the electrode process of phenol oxidation by cyclic voltammetry. The experimental conditions to determin phenol were optimized. The current analytical signal of phenol oxidation process is linearly dependent on the concentration in the range of 0.001 - 1.0 mg / l with the accumulation time of 30 s, electrolysis potential of 0.1 V, and scan rate of 30 mV / s. The correctness of the technique was tested by the "entered - found" method.
