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.
