Ecotoxicity Measurements of Degraded Textile Dye by Electrochemical Process Using Boron-Doped Diamond Electrodes

摘要

This work presents aspects related to production, characterization and application of boron-doped diamond (BDD) films deposited on Titanium (Ti) substrate at two different doping levels. The electrooxidation of the Brilliant Green dye is studied considering the influence of the film doping levels. The electrochemical degradation results were investigated by spectroscopic techniques UV/VIS analysis, Total Organic Carbon (TOC), High Performance Liquid Chromatography (HPLC) and toxicity against the Gram-negative bioluminescent marine bacterium Vibrio fischeri analysis. The BDD electrode with the higher doping level showed, the better efficiency. On the other hand, the lower doped electrode showed the lower toxicity level for the degraded solutions.
