A method for the kinetic determination of nanogram amounts of NO2– is based on its acceleration of the rate of bromination of pyridine-2-aldehyde 2-pyridylhydrazone in acidic medium. The reaction is followed by fluorometry while monitoring the formation of a fluorescent product using an excitation wavelength of 291 nm and an emission wavelength of 432 nm. The method was applied to drinking water anal., with a detection limit of 4.6 ng/mL and recoveries 92-105%. The relative standard deviation of the method is 2.4%. The major advantages of this method are simplicity, absence of a reagent blank, selectivity, and sensitivity.
