摘要: 本研究係以波長365nm的紫外光配合二氧化鈦,進行光催化二氧化鈦分解 二氯乙烯之可行性實驗,並探討反應物濃度、停留時間、溼度、氧氣含量 及光照強度等操作參數對異相光催化反應之影響,同時並建立包含以上操 作參數的反應動力模式,最後再對反應後的最終產物作分析,以瞭解最終 產物的影響因子及礦化情形。
The photocatalytic decomposition of dichloroethylene was investigated by near ultraviolet light illuminatedtitanium dioxide . The purpose of this investigation was to understand the feasibility of photocatalytic decomposition of dichloroethylene. The effects of reaction parameters on heterogeneous photocatalytic reaction were also studied. The reaction parameters included dichloroethylene concentration , relative humidity , retention time and light intensity . In addition, the reaction kinetic was discussed. The Langmuir- Hinshelwood kinetic equation was commonly used to rationalize the reaction kinetric of titanium dioxide heterogeneous photocatalytic reaction.
