Abstract:	利用化學氧化分解程序進行有機毒性物質之排除，為近來頗受重視之研究方向。本計畫利用芬頓氧化系統，對於六氯苯(HCB)採取化學性氧化分解程序。研究成果顯示，採用化學氧化降解，高含氯量之芳香族化合物具有抵抗化學氧化之特性，因此Fenton系統針對這類化合物並無明顯降解效果。若以Fenton系統處理低含氯量之 135-三氯苯、13-二氯苯、14-二氯苯，其降解率可達72%、88%與86%。然而若在環境基質溶液中進行化學氧化作用，因為溶液之有機質與微生物的干擾，其化學氧化效率會明顯降低，此外研究結果亦顯示，較低有機質將有助於氯苯化合物之氧化降解。 Recently, a method of chemical oxidation treatment to deplete the HCB pollutions were discussed. In this study, the degradations of HCB were made by chemical oxidation procedures. The results suggested that the highly chlorinated aromatics were more resistant to Fenton oxidation than less chlorinated ones. The less chlorineated compounds, 135- trichlorobenzene, 13-dichlorobenzene, 14- dichlorobenzene were treated by Fenton system with decomposition ratios of 72%, 88% and 86%, respectively. The organic matters in the environmental water bodies and media solutions had reduced the extent of oxidation. In this study, we also evaluated how the organic contents affected the efficiency of Fenton system.
