Anodic Decomposition of Toxic Compounds (Anodic Mineralization)
Electrochemical oxidative treatments to degrade or to mineralize persistent organic substances by converting them to safe and low-molecular-weight substances which are positioned as an important technology to reduce the environmental impact of wastewater and to reuse the water as a resource.
Electrochemical treatment involving anodic decomposition is a very promising method for the reduction of toxic pollutants dissolved in wastewater. It is important to select the proper anode materials to optimize this technique, because the electrolytic products strongly depend on these materials as well as the operating conditions such as the current density and temperature [1, 2].
Concerning the anodes, several types of materials have been developed, which are classified as follows: carbon (amorphous carbon, graphite), novel metal or metal oxides (Pt, IrO2, RuO2), and nonnovel metal oxides (PbO2, SnO2, TiOx). In recent years, several researchers have been investigating the...
