The fluorimetric determination is based on the diazotization reaction of nitrite with a fluorescent dye, tetraamino zinc (II) phthalocyanine in an acidic medium. Under the optimum experimental conditions, nitrite can be determined in the range 10− 6–10− 4 mol·L− 1 with the detection limit 2.04 × 10− 8 mol·L− 1. The proposed method has been successfully applied to the determination of nitrite in various water samples. The results compared favorably with the results from a standard ISO certified method. |
