【摘要】 采用湿式氧化法分别处理含苯酚、苯胺和硝基苯的废水,研究了反应温度(160～220℃)对氧化反应的影响。苯酚的氧化经历两步,即诱导期和快反应期,而苯胺的氧化反应无诱导期。有机污染物的反应活性与其结构和氧化反应的模式有关,在一定的时间内,3种有机污染物的氧化去除率的次序为:苯酚>苯胺>硝基苯。更多还原

【Abstract】 Liquid-phase oxidation of aqueous solutions of phenol, nitrobenzene and aniline was studied employing oxygen as the oxidant.The influence of temperature (160～220 ℃) on wet air oxidation of these compounds was investigated.Phenol oxidation proceeds in two steps:an induction period during which little of the organic was oxidized, followed by a rapid reaction period during which most of the organic was destroyed,while for aniline, the removal rate is linear with the time.The order of the reactivity of these three compounds in fixed time is:phenol>aniline>nitrobenzene,which is correlated to their molecule structures and reaction models.更多还原
