Abstract

A novel and simple spectrophotometric method is developed for the determination of nitrite in water by using the self-coupling diazotization reagent 2-amino-6-chlorobenzoic acid and UV light illumination. The method only involves one reagent and one step, which can be easily applied to the determination of nitrite and tolerates many foreign anions' effects under acidic conditions.
