Abstract
The physiochemical and electrochemical properties as well as the activity of novel Ti/B-diamond electrodes for anodic oxidation of various dyes were investigated. It was found that the Ti/B-diamond electrodes were much more active than Ti/Sb2O5-SnO2. All dyes tested, including orange II and 16 reactive dyes, could be mineralized effectively at Ti/B-diamond, with current efficiencies being 51.0-90.2%. The energy consumption ranges from 8.9 to 17.9 kW h/m3. Operating variables could affect the process efficiency significantly. Low current density, high pH, and high temperature are beneficial for dye degradation.
