邻硝基甲苯复合化学氧化降解研究

Degradation of o-Nitrotoluene by Complex Chemical Oxidation

应用Stopped_Flow光谱仪反应器研究了邻硝基甲苯污水在 2 93K和 pH =3.2～10时的复合化学氧化 (O3/H2 O2 )降解过程 ,并获得了反应动力学常数 .

The complex chemical oxidation degradation of o _nitrololuene in waste water was investigated at 293 K and in the pH values ranging from 3.2 to 10 by utilizing the Stopped_Flow Spectrometer reactor. The reaction kinetic data were obtained by the regression analysis. The reaction mechanism of chemical oxidation for o _nitrotoluene was discussed through experimental study and theoretical analysis, and the hydroxyl radical oxidation of o _nitrotoluene is predominant.
