Data on Photoelectrochemicals Detailed by Researchers at State University (Efficient Photoelectrochemical Reduction of Nitrite to Ammonium and Nitrogen Containing Gaseous Species Using Ti/TiO2 Nanotube Electrodes)

By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Biotechnology have been published. According to news reporting originating from Araraquara, Brazil, by NewsRx correspondents, research stated, "The present work describes a suitable method for removing nitrite contaminant from water by using a photoelectrocatalytical method."

Our news editors obtained a quote from the research from State University, "A Ti/TiO2 nanotube electrode was used as a cathode under UV irradiation and applied potential of -0.2 V vs. Ag/AgCl and it led to 100% of nitrite removal after 6 min of photoelectrolysis conducted in NaCl 7 mmol L-1, pH 7 and in absence of dissolved oxygen. Nitrite reduction on Ti/TiO2 photoelectrodes occurs in the cathodic compartment cell via electrons generated when the electrode is under UV irradiation leading to a generation of 7% of remaining ammonium and 93% nitrogen containing gaseous species after 6 min of treatment."

According to the news editors, the research concluded: "The results indicate that the method could be an efficient tool for the treatment of nitrite in water containing nitrite."
