建立了UV/H2 O2氧化水中苯酚的动力学模型。该模型是基于基本的化学和光化学反应，引发过氧化氢的光解成羟基自由基。通过使用从公开文献中获得的实际UV/H2 O2过程的实验数据来验证该模型。使用这些数据和发达的动力学模型，动力学速率常数苯酚中间体，邻苯二酚和对苯二酚，估计。此外，最佳的初始过氧化氢浓度估计通过验证模型。© 2007 Wiley Periodicals，Inc. Int J Chem Kinet 40：34-43，2008
A dynamic kinetic model for the oxidation of phenol in water by an UV/H2O2process is developed. The model is based on the elementary chemical and photochemical reactions, initiated by the photolysis of hydrogen peroxide into hydroxyl radicals. The model is validated by using experimental data obtained from the open literature for an actual UV/H2O2process. Using those data and the developed kinetic model, kinetic rate constants for phenol intermediates, catechol and hydroquinone, are estimated. Moreover, the optimum initial hydrogen peroxide concentration is estimated by means of the validated model. © 2007 Wiley Periodicals, Inc. Int J Chem Kinet 40: 34–43, 2008
