Abstract: In this research interaction between sulfur gases (SO2,H2S,CS2)with carbon nano tube Are discussed. THE anode carbon contain sulphur which reacts with oxygen formed during electrolysis and give SO2,and  also reacts with moisture in the raw material  during electrolysis gives H2S ,in addition reacts with carbon in anode during electrolysis gives CS2. In the atmosphere this gas reacts with more oxygen and water vapor and sulphuric acid formed. Lennaed-Jones potential was used for gas-gas and gas-carbon nanotube interactions and the potential parameters for the carbon-gas and carbon-carbon interactions were obtained from the Lorenz-Berthelot combining rules show that the adsorption of this gases on carbon nano tube impossible. And highest interaction is between so2 and carbon nano tube.
