Inves tigating the Types of Electrodes in the Electrooxidation Process of Indus trial Was tewater Treatment

Electro-oxidation is a type of advanced oxidation process, which is based on the use of electrochemical principles to protect the environment. Similar to traditional oxidation processes, oxidizing agents in electrochemical oxidation usually include hydroxyl and sulfate radicals, hydrogen peroxide, chlorine, and ozone. But traditional was tewater treatment methods, compared to the electrochemical process, do not have enough ability to remove toxic and dangerous pollutants. The overall performance of the electrochemical reaction, as well as the rate of production of side products, is highly dependent on the properties of the electrode used. The type of electrodes plays a very important role in the selectivity and efficiency of electrochemical processes. Based on their gender, anodes cause partial and selective oxidation. The use of semiconductor electrodes for the decomposition of organic pollutants in was tewater is also discussed. Among the types of anode electrodes that are mos t used in the electrooxidation process; We can mention PbO2, WO3, SnO2/Sb, RuO2/IrO2/TiO2 and BDD. The electrodes used in the electrooxidation process are made in different ways, including thermal decomposition, laser heating, and electrical deposition, according to the material and function. Also, their performance depends on operating conditions such as concentration, voltage, anode area and cathode material.
