摘要
研究了水溶液中邻硝基甲苯在有O_3或O_3/H_2O_2情况下的氧化反应过程,并建立了动力学模型。在293K、pH值3～10条件下对反应进行测定。实验结果表明,臭氧衰减速率对于O_3来说反应级数为1,而对于邻硝基甲苯来说则随pH值变化和H_2O_2的有无而变化,实验结果与理论预测相吻合。
Study on oxidation of aqueous-phase of o-nitrotoluene by dissolved ozone and ozone-hydrogen peroxide mixtures has been conducted and the kinetic models have been established. The experiments were carried out at 293K with pH values varying from 3 to 10. Data of the experiments showed that the oxidation kinetics was first order with respect to the ozone concentration, and the reaction order in nitrotoluene varied with pH values and hydrogen peroxide which existed or not. The experimental results are in agree- ment with the theoretical model developed.
