title: [The conversion from CS2 to COS by spark discharge].
abstract: Spark discharge method was used to take simulative investigations on the conversion reaction from CS2 to COS by lightning. The results showed that 1.33 x 10(3) Pa CS2 could act with O2 or H2O in the atmosphere (25 degrees C, 10(5) Pa) under electric discharge conditions (V = 3000 V), and COS was produced as well as other species such as CO, CO2, SO2 and so on. Factors such as CS2 concentration, water vapor and discharge time played important roles in the formation of COS. Based on these results and several theories, possible mechanisms of correlative processes during thunderstorms were proposed here, which could contribute to give evidence for the conversion from CS2 to COS by lightning during thunderstorms.
