%X Chemiluminescent technique was applied for the determination of nanomolar quantities of nitrate and nitrite. Suspended particles and chromaphores did not interfere and were hence not necessary to be removed. The optimal experimental conditions with detection limit of 10 nmol/L were set up in the laboratory. The relative standard deviation was 5% at the 200 nmol/L level and 3% at the 400 nmol/L level. At wider detected range, greater accuracy and precision were obtained for this technique comparing to the conventional spectrophotometric methods. Consistent results were obtained when the concentrations of nitrate and nitrite in seawater and river water samples were measured using these two methods.
