RESUMO
Cylindrical diamond electrodes are developed with area up to 75 cm2 and were applied in electrochemical degradation of organic pollutants in wastewater. Systematic study was carried out to deposit conductive and well-adherent diamond onto several materials. These electrodes were characterized in term of their material and electrochemical properties by scanning electron microscopy (SEM), Raman and energy dispersive spectroscopy, voltammetry, nanoindentation, four points probe, pull-off test. The oxidation of several micro-pollutants in water were studied and monitored by UV/Vis absorbance, Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC). The electrodegradation results employing cylindrical boron-doped diamond (BDD) electrodes were satisfactory compared with best results obtained with conventional plate-shape BDD electrodes.
