N-FENYLBENZYLAMIN JAKO NOVÉ KOPULAČNÍ ČINIDLO PROSPEKTROFOTOMETRICKÉ STANOVENÍ DUSITANŮ

Abstrakt

This paper introduces a new reagent N-phenylbenzylamine for determination of nitrite
in water and aqueous solutions. The reagent in the acidic medium coupled with diazotized
dapsone to form the azo dye. The reaction provides a sensitive and reproducible determination
of nitrite without special modifications of reaction conditions. The detection limit is
0.07 μg.ml-1, and linear range 0.1-2.0 μg.ml-1 of nitrite. This method significantly enhances
application of N-phenylbenzylamine as an important reagent used in the analysis of some
chemical warfare agents and industrial pollutants.
