Biography
Pralay Gayen has expertise in the area of electrochemical treatment of water and wastewater matrix. His research objective is to develop effective, highly robust and highly selective material to detect antibiotics, degrade different organics and inhibit perchlorate formation in water matrix as all these compounds pose serious health hazard. He has been using boron-doped diamond (BDD) electrodes for wastewater treatment as they are efficient at oxidizing recalcitrant organic compounds through electrochemical oxidation. He has also been using differently fluorinated BDD electrodes to prevent perchlorate formation without affecting organic oxidation as perchlorate is carcinogenic and formed through electrochemical oxidation of chloride. He also fabricated a sensor comprising BDD electrodes modified by carbon nanotube and nafion for the electrochemical detection of antibiotic (ciprofloxacin) in water and wastewater matrix as the presence of antibiotics for a long time will cause potential emergence of drug resistant bacteria.
