    摘要: 本研究利用含浸氯化鐵的樹脂觸媒充當異相催化反應催化劑,以0.5 M的FeCl3 ‧6H2O含浸濃度,0.5%(w/v)樹脂觸媒劑量、0.1M的H2O2劑量、控制起始pH值為7與反應溫度80℃進行五氯酚氧化程序,並進行重複回收樹脂觸媒之可行性評估,經3次回收使用的樹脂觸媒仍具有高的五氯酚氧化效率,預期可降低五氯酚水相污染整治復育之經費。利用Microtox生物毒性測試,在最佳操作條件下五氯酚經本系統氧化40分鐘後其毒性偵測值為0,在模擬地下水中氧化處理五氯酚,隨地下水性質之改變,Fe+3樹脂觸媒/H2O2系統之氧化效率略有不同,但仍可成功且快速的氧化地下水中五氯酚。
    The object of this study was focusing on the oxidation treatment of pentachlorophenol (PCP) utilizing the heterogeneous resin catalyst prepared by the immersing method. The treatment efficiency and conditions was discussed in a batch reactor. In order to investigate the feasibility of recycling Fe+3-resin catalyst, the batch condition was set as 0.5% (w/v) catalyst dosage, 0.1 M H2O2, pH 7, and reaction temperature 80℃. The used catalysts were recovered after oxidation reaction and were reused in the oxidation of PCP in aqueous solution for four successive times. The results showed that the same Fe+3-resin could be reused for at least three cycles of PCP oxidation in aqueous solution. Moreover, it also indicated that the toxicity of oxidation product was almost decomposed after 40 minutes oxidation. The high efficiency of oxidation and toxicity test showed that the Fe+3 resin/H2O2 system would be the referee of polluted groundwater remediation processes.
