On the performance of Fe and Fe,F doped Ti-Pt/PbO2 electrodes in the electrooxidation of the Blue Reactive 19 dye in simulated textile wastewater.
Chemosphere. 2007 Feb; 66(11):2035-43.C

Abstract

The electrochemical performance of pure Ti-Pt/beta-PbO2 electrodes, or doped with Fe and F (together or separately), in the oxidation of simulated wastewaters containing the Blue Reactive 19 dye (BR-19), using a filter-press reactor, was investigated and then compared with that of a boron-doped diamond electrode supported on a niobium substrate (Nb/BDD). The electrooxidation of the dye simulated wastewater (volume of 0.1 l, with a BR-19 initial concentration of 25 mg l(-1)) was carried out under the following conditions: current density of 50 mA cm(-2), volume flow rate of 2.4 l h(-1), temperature of 25 degrees C and electrode area of 5 cm2. The performances of the electrodes in the dye decolorization were quite similar, achieving 100% decolorization, and in some cases 90% decolorization was achieved by applying only ca. 0.3 A h l(-1) (8 min of electrolysis). The reduction of the simulated wastewater organic load, monitored by its total organic carbon content (TOC), was greater for the Ti-Pt/beta-PbO2-Fe,F electrode obtained from an electrodeposition bath containing 1 mM Fe3+ and 30 mM F-. In this case, after 2 h of electrolysis the obtained TOC reduction was 95%, while for the pure beta-PbO2 and the Nb/BDD electrodes the reductions were 84% and 82%, respectively.
