• Sulfur dioxide in aqueous solution (HSO_3^-) was determined by chemiluminescence method based on a reaction between SO_2 and KMnO^ in the liquid phase. Sulfur dioxide in slightly alkaline solutions containing formate ion (2μM) was stable against oxidation by dissolved oxygen for the period of measurement. Chemiluminescence yield was proportional to HS0_3^1 concentration in the range of 0.8-100 ng SO_2 ml^<-1>, and the reproducibility was assured to be 2-6% in relative standard deviation. While some oxidizing agents, halide ions, transition metal ions and nitrite ion decreased the light yield to some extent, no interference was observed with regard to most of coexistent ions. The proposed method is applicable to determination of ppb level SO_2 in rain water.
