Abstract

The wastewater produced by the textile industry is replete with numerous contaminants that are known to be hazardous to aquatic and terrestrial living systems. Particularly dangerous contaminants in the textile sector that defy traditional degrading techniques include synthetic dyestuffs. In order to protect the environment, this chapter reviews current advancements in the electrochemical treatment of wastewater containing synthetic organic dyes by anodic oxidation. The mechanisms of electrochemical oxidation in anodic oxidation processes are thoroughly described. The electrochemical degradation of wastewater has been studied using a wide variety of electrodes. As a result, this paper attempts to summarize and discuss the most significant and recent studies on the use of anodes for the removal of organic synthetic dyestuffs that are currently available in the literature.
