摘    要:本文研究了水溶液中1-萘酚在鼓泡反应釜内臭氧氧化的消失动力学,考察了pH值、温度、自由基清除剂和1-萘酚的起始反应浓度等因素对反应的影响。结果表明,pH值、反应温度的提高有利于1-萘酚的降解。1-萘酚初始浓度低时其消失速率较高。该反应是有自由基反应贡献的分子臭氧氧化反应。在重碳酸盐存在下,1-萘酚的臭氧氧化降解符合一级反应动力学。

关 键 词:臭氧  1-萘酚  动力学  氧化降解  有机污染物  废水

Abstract:In this paper, the reaction of ozone and 1-naphthol in aqueous solution in the bubble reactor was studied. The influence of pH, temperature, initial concentration of 1-naphthol and the free radical inhibitor on the reaction kinetic was investigated. It was found that an increase of pH of the solution leads to an increase of the elimination rate of 1-naphthol, while temperature doesn't significantly affect the reaction rate. The lower initial concentration of 1-naphthol showed more the elimination rate. The reaction between ozone molecule and 1-naphthol was enhanced by the reaction of the radicals with 1-naphthol. In the presence of bicarbonate ions, the reaction followed pseudo first-order kinetic.
Keywords:ozonation    1 - naphthol  kinetics
