Determination of the volatile products during urea oxidation on platinum by on line mass spectroscopy

Abstract The formation of volatile products during the electrochemical oxidation of urea on platinum was followed by on line mass spectroscopy. Next to the main products, CO 2 and N 2 , nitrogen oxides were detected in phosphate buffer and Krebs—Ringer solutions during a potential scan. The identification of products delivering identical mass signals was performed by using 15 N-labelled urea.
