摘要：

The gas phase reaction of ozone with dimethyl sulfide (DMS) has been studied in our self-made chamber. Experiments were conducted under supposedly pseudo-first-order decay conditions, keeping [DMS](0) > 10[O-3](0), but having different combinations of [DMS](0) and [O-3](0), Cyclohexane was added into the reactor to eliminate the effect of OH radicals. A value of (1.04 +/- 0.21) X 10(-19) cm(3) molecule(-1) s(-1) for rate constant was obtained under room temperature of about 301 K. The wall effects and the role of cyclohexane are discussed. Our results enrich the kinetics data of atmospheric chemistry, and further confirm that the gas phase reaction of DMS with ozone is not important for the loss of DMS in the atmosphere.
