【摘要】 芳香化合物的Fenton氧化性能与其结构密切相关,芳环上取代基位置、数量和种类的不同会对其降解速率产生显著影响。单氯酚3种异构体降解速率大小依次为:3-氯酚>4-氯酚>2-氯酚;氯酚的反应活性随芳环上Cl取代基数目的增加而下降,2-氯酚、2,4-二氯酚和2,4,6-三氯酚的反应活性遵循下列顺序:2-氯酚>2,4-二氯酚>2,4,6-三氯酚;芳环上的取代基对芳香化合物的Fenton氧化性能有很大影响,苯胺、氯苯和硝基苯降解速率依次为:苯胺>氯苯>硝基苯。更多还原

【Abstract】 The rates of degradation of aromatic compounds by Fenton oxidation are affected by(position,) number and type of the substitute group.The degradation rate of 3-chlorophenol is fastest,(followed) by 4-chlorophenol and then 2-chlorophenol.The reactivity of chlorophenols decreases with more chlorine on the aromatic ring;the oxidation rate of chlorophenols in declining order is 2-chlorophenol>(2,4-dichlorophenol>2,) 4,6-trichlorophenol.The Fenton reactivity of the three single substituted aromatic compounds in declining order is aniline>chlorobenzene>nitrobenzene.更多还原
