Abstract The feasibility of multifunctional detection of NO, CO, and SO2 in ambient air, based on the chemiluminescent reaction of these pollutants with atomic oxygen, was studied in a laboratory prototype detection system. Using this approach, concentrations as low as 5 ppb NO have been detected, and laboratory evidence predicts detection capabilities for SO2 to be below 1 ppb. The CO-O reaction produced insufficient glow for adequate detection below approximately 100 ppm. A linear relationship was established between glow intensity and pollutant concentration in all cases. Nitrogen dioxide interfered with NO detection but no other serious interference problem was observed. Here, the responses of NO2 and NO were identical, and the chemiluminescent reaction with atomic oxygen provides a sensitive means for detecting both NO and NO2 in ppb concentrations. In both the NOx-O and the SO2-O reactions, the present detection limit characteristics of the laboratory apparatus can be significantly enhanced by further optimization of the system. (Author)
