COLORATION REAGENT OF NITRATE IONS AND METHOD FOR DETECTING AND QUANTIFYING NITRATE IONS USING IT

摘要

PROBLEM TO BE SOLVED: To provide a coloration reagent of nitrate ions having high precision and capable of simply detecting nitrate ions, and a method for detecting and quantifying nitrate ions using it.;SOLUTION: The coloration reagent includes a naphthalene derivative such as 8-anilino-1-naphthalenesulfonic acid (1, 8-ANS) or 6-p-toluidino-2-naphthalenesulfonic acid (2, 6-TNS) and can detect nitrate ions by the coloration reaction of the naphthalene derivative and nitrate ions. The method for detecting and quantifying nitrate ions includes the stage of performing coloration reaction of the coloration reagent and nitrate ions in an aprotic solvent.;COPYRIGHT: (C)2010,JPO&INPIT
