Based on the catalytic effect of trace nitrite on the oxidation of rhodamine 6G by potassium bromate, and the reduction of nitrate by zinc powder, a method for the simultane-ous determination of nitrite and nitrate has been studied. The method is characterized by high sensitivity, simplicity and rapidity. It has been used to determine nitrite and nitrate in water and beverage with satisfactory results.
