![]() We summarize the pros and cons of electrochemical methods for these anions and highlight the possibility of electrochemical techniques in water treatment from industrial perspective. Also, specific focus is paid for the removal of perchlorate and nitrate anions, which are often present in drinking water in considerable amount and are harmful for human body. In this chapter, we highlight some of the recent progress made in the field of water treatment by electrochemical techniques. ![]() In this respect, electrochemical techniques have emerged as versatile tool to address these challenges owing to their simplicity, specificity, reliability, and cost effectiveness. However, their practical feasibility is limited in domestic water purification because of the generation of secondary contamination. The separation technology includes ion-exchange, reverse osmosis, adsorption, membrane filtration, and electrodialysis techniques, whereas biological and chemical reduction falls under transformation technology. So far, various techniques have been utilized by researchers for water treatment, which usually involves the process of separation and/or transformation. ![]() ![]() Anodic oxidation and electro-Fenton processes failed to remove generated arsenate in the system but found effective to oxidize arsenite completely from its initial concentrations of 1 mg/L and 10 mg/L. This may involve desalination or purification of water by removing specific pollutants, salts, ions, or other species. The present article examines the possibility of electrochemical advanced oxidation processes to remove arsenite from water medium. ![]() The process of improving water quality for the desired purpose is generally referred to as water treatment. ![]()
