A simple, rapid and selective fluorimetric method using acridine orange for determination of 0.4— 5.0 ppm nitrate has been described. Effects of various parameters, like sulphuric acid concentration, reaction time, temperature, foreign species etc. have been discussed. The method has been used for the determination of nitrogen dioxide in air samples of Durgapur industrial area (Burdwan District).
