Abstract

The outdoor smog chamber was used to thorough investigate the rate constants of gas-phase reaction between dimethyl sulfide (DMS) and ozone (O₃) under conditions of relative humidity 55.0%–67.8% at (296±2)K for the first time. The rate constants were measured, at a total pressure of 1 atm, to be (10.4±0.2) × 10^-19 cm³·molecule^-1·s^-1 at relative humidity of 67.5%±0.3% at 298K, (10.1±0.1) × 10^-19 cm³·molecule^-1·s^-1 at relative humidity of 66.5%±0.5% at 296K, (7.75±0.39) × 10^-19 cm³·molecule^-1·s^-1at relative humidity of 64.8%±0.1% at 294K and (3.42±0.21) × 10^-19 cm³·molecule^-1·s^-1at relative humidity of 55.8%±0.8% at 295K. Base on these results, it is possible to see the reaction of O₃/DMS in the presence of water vapor as an important sink for DMS in the earth atmosphere.

Fig.1 Time dependent mixing ratio of O measured in the ozonolysis experiment. It was carried out in the dark chamber, with an initial gas mixture of 5.4 × 10 molecules·cm ozone and 1.2 × 10 molecules·cm CO at relative humidity of 55%±10%. Monitoring started 30 min after injection
