Abstract

A new fairly selective, simple and sensitive spectrophotometric method for the determination of trace amounts of nitrite was developed, based on that nitrite reacts with safranine T in HCl medium to form a nitroso- safranine T with the maximum absorption peak at 350 nm. Optimum reaction conditions and other important analytical parameters for the reaction system were established. Beer's law was found to obey for nitrite in the concentration range of 0-1.8 μg mL-1 with molar absorptivity of 2.531 × 104 L mol-1 cm-1 and Sandell's sensitivity of 0.0018 μg cm-2. The effect of interfering ions on the determination is described. The recommended method was applied for the determination of nitrite in different water samples with satisfactory results in agreement with those of the AOAC recommended sulfanilamide-[N-(1-napthyl)ethylenediamine hydrochloride] (NED) method.
