Ruthenium Iridium Coated Titanium Anode for Electrochemical Treatment of Landfill Leachate

Electrochemical processes are considered a very effective method for decolorization and decontamination of wastewater from textile and dyes industries. The electrode is a crucial part of the electrochemical process. The right choice of an electrode material makes the process very effective and improves its efficiency because the mechanism driven by the process as well as the degradation product depends upon the anode material. High efficiency and high stability are the most desirable properties of electrodes. Mixed metal oxide (MMO) coated titanium electrodes are titanium based electrodes containing conductive metal oxide coating. These electrodes have some desirable properties such as high surface area, high electrical and mechanical strength and excellent electro-catalytic properties and performed good oxidation of pollutants.

Pharmaceutical industry effluents are usually characterized by high BOD and COD, which are highly toxic to biological life. Electrooxidation, which relies on the generation of very reactive hydroxyl radicals has been used to decontaminate pharmaceutical wastewater and has proven to be an effective manner.

Titanium anodes with Iridium Oxide Coating for Electrochemical Degradation of Organic Pollutants: Electrochemical oxidation is an effective method to treat high-concentration wastewater, it can degrade complex organic pollutants in wastewater into non-toxic small molecular organic compounds or carbon dioxide and water through mineralization of various organic pollutants.

In the electrocatalytic oxidation process, different electrode materials behaviors various efficiency. Choosing an appropriate electrode material is an effective way to improve the efficiency of the electrochemical degradation result. Dimensionally stable anode (DSA) has good stability and catalytic activity and has been widely used. It is a kind of noble metal oxides (such as RuO2 and IrO2) with strong corrosion resistance and high stability coated on the titanium. This electrode has the advantages of high oxygen evolution potential, low cost, and easy operation, AUE manufacture a nanocrystal iridium oxide coated titanium anodes for electrochemical degradation of organic pollutants by thermal decomposition method, which shows high chemical oxygen demand (COD) removal rate and efficient degradation result.
