| Abstract: | In order to apply plasma technology in environmental protection, and find a new way to treat air Pollutants, the experiment selected CF2ClBr,a kind of chemical stable extinguisher as the research material, and the innuence of He,N2,O2 and air in degradatign of CF2ClBr by plasma was studied. and CF2ClBr was successfully degraded at normal pressure. The main products of degradation were similarly to only degrading CF2ClBr when He or N2 was added to the degradation system. The degradation products was mainly CF2O, Br2, Cl2 in the presence of O2 and air. The order of extra gases influencing degradation of CF2ClBr was following:He< N2< O2, air. |
