| 中文摘要 |
| 利用介质阻挡放电方法对环境污染物ＣＦ2ＣｌＢｒ进行了等离子体降解的研究．在前人对该体系的降解产物分析及活性粒子推测的基础上，采用动态反应装置得到了等离子体的发射光谱，进一步确证了等离子体系中出现的ＣＦ2、ＣＦＣｌ、Ｆ、Ｃｌ、Ｂｒ等主要自由基，并从中推出了等离子态气体可能发生的自由基反应．同时通过发射光谱的分析，近似得到该体系的平均电子能量约为２．４２ｅＶ |
| 英文摘要 |
| The plasma decomposition of pollutant CF2ClBr was studied by Dielectric Barrier Discharge method.The emissive spectrogram of the plasma system was attained through a dynamic apparatus.With the spectrogram and the previous studies about the decomposition products and possible active particles in this system,several free radicals such as CF2、CFCl、F、Cl and Br were proved to be the main radicals that come into being in the reaction progress.And the possible radical reactions in the plasma system were inferred.The electron energy in plasma was also studied approximately.It's about 2.42eV. |
