Abstract
Official abstract text for this publication.
A method of determining a concentration of nitrate includes mixing an acid with a first mixture comprising an aldehyde, a chloride and at least one of a nitrate sample and distilled water so as to obtain a second mixture. The second mixture is reacted with a phenol so as to develop a color in a third mixture after a reaction time. The concentration of nitrate is determined colorimetrically with the third mixture.
