Electrochemical Treatment Of Anionic Surfactants In Synthetic Wastewater With Three-Dimensional Electrodes

Bo Wang, Wuping Kong, Hongzhu Ma, Lin Gu


The electrochemical oxidation of anionic surfactants (sodium dodecyl benzene sulfonate, DBS) contained in simulated wastewater treated by three-dimensional electrode system with combined modified kaolin served as packed bed particle electrodes and Ti/Co/SnO2-Sb2O3 anode was studied, the chemical oxygen demand (COD) removal of pollutants in the solutions was also investigated. The results showed that the three-dimensional electrodes could effectively remove anionic surfactants. Its COD removal efficiency was 86% much higher than those of Ti/Co/SnO2- Sb2O3 electrode used singly and modified kaolin employed singly at the same condition of pH 3 and 38.1 mA/cm2 current density. At the same time the influence of pH and current density on COD removal efficiency with three-dimensional electrodes was also investigated, respectively.
