Abstract

The present paper reports the utilization of a boron-doped nanocrystalline diamond film (BDD) in electrochemical oxidization (ECO) process of organic phenol compound in 0.1 M H2SO4 water solution. The nano BDD films were synthesized by microwave plasma chemical vapor deposition (MWPCVD), and then characterized by Raman spectroscopy and SEM before and after the electrochemical oxidation treatment. For the ECO treatment performed to the test sample solution, an observation of the first and the last voltammetric plots exhibited a qualitatively differences between the two plots where the first one represent the initial concentration and the last one the signal produced by the organic solution after treatment. UV-Vis analysis through the application of a standard calibration curve, quantitatively confirmed the composition of phenol remaining in the sample solution subdued to the ECO treatment.
