نویسندگان
چکیده
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, and linear range 0.1-2.0 μg.ml 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.
