近來氯苯酚類化合物被大量且廣泛的使用於日常生活中，屬於致癌性與致畸性毒物，其主要來源是化工、煉油、造紙、煉焦、塑料等工業廢水；另外有時在水中加氯消毒也可能與水中有機物質結合形成氯苯酚類化合物，目前以TiO2為催化劑進行光催化氧化反應之方法為一新穎技術。
反應結果顯示，本實驗室所發展之改良式反應裝置對於4-氯苯酚之分解確實也有良好顯著地效果，關於影響光催化反應處理程序之因子中，反應初速率r0值隨4-氯苯酚初濃度、空氣流量、光強度等增加而上升。本反應裝置之最佳操作條件為TiO2濃度0.49 g/L、反應溶液體積60 mL、初pH值3.15、空氣流量7 L/min及光燈管數目12支等，會得到最佳分解效果。
改良式反應裝置在光催化反應各項變因對於4-氯苯酚及3-氯苯酚大致有相同之趨勢，而對於分解速率而言4-氯苯酚之分解速率較3-氯苯酚之分解速率小。

The Chlorophenols is carcinomatous, mutation remains and their wide
applications, so the investigation of photodegradation of Chlorophenols
was attached to the waste water treatment in daily. Update photocatalyic
degradation of the chlorinated aromatic compounds appears to be a
promising method, in particular, when using TiO2 as a stable and
inexpensive photosensitive material.
The results show that the improvable reaction equipment is good
decomposition efficiency to photodegradation reaction of 4-chlorophenol,
too. The initial rate of the 4-chlorophenol oxidation is increasing with
the initial concentration, the flow of inlet air, the incident light
intensity. The optmum condition under considering the cast are at the
0.49 g/L concentration of TiO2, the 60 mL volume of initial reaction,
the 7 L/min flow of inlet air, the 3.15 of initial pH and 12 number of
solar lamp.
There is similar trend between 4-chlorophenol and 3-chlorophenol with
the improvable reaction equipment, and the photodegradative rate of
4-chlorophenol is smaller than 3-phlorophenols.
