Pharmaceuticals are among the notorious organic groups that are synthetically being produced right now. Numerous pharmaceutical compounds are produced worldwide on a daily basis. Release of such compounds through various pathways in the environment causes toxicity even if it’s present in micrograms. Among the various classes of pharmaceuticals, antibiotics are the most widely prescribed and used class. Many conventional treatment technologies like the physical separation techniques and biological treatment processes are not efficient enough to completely remove these antibiotics from the media. Electrochemical techniques have emerged as promising new technology in this regard. Electrochemical techniques are divided into electrochemical separation techniques and electrochemical advanced oxidation techniques. The electrochemical separation techniques separate the pollutant from the solution only and include techniques like electrocoagulation, electro-flotation and internal micro electrolysis. The electrochemical oxidation technique has hydroxyl radical (·OH) as the main degrading agent produced in-situ during the electrolysis process at the anode surface. This hydroxyl radical is considered as the second most strongest oxidizing agent after Flourine. Much research has been done on the electrodes that are responsible for electrochemical oxidation. pH, current density, time of electrolysis, electrlyte concentration all play a vital role in the process completion. In spite of their efficiency in an organic matter degradation, the electrodes responsible for bringing out this process are quite expensive and a competiton between different oxidizing agents might develop in the reaction cells which may bring down the process efficiency.
