| 摘 要： | 利用天然锰氧化物矿物在酸性条件下的强氧化性,研究其氧化水中苯酚的动力学,模拟锰氧化物矿物氧化苯酚的反应过程。通过测定初始浓度为100~1000 mg/L,pH值为1~2,温度为293~333 K时不同氧化时间锰氧化物矿物对苯酚的氧化结果,比较伪一级和伪二级反应方程的线性拟合情况;结果表明,该反应动力学曲线用伪二级反应模型拟合时相关系数高于用伪一级反应方程线性的拟合,所以这个反应可用来模拟伪二级反应。根据动力学数据得出Arrhenius反应活化能Ea为11.62 kJ/mol,说明温度对该反应影响不显著,且是一个扩散控制反应。

| Abstract: | The kinetics of oxidizing phenol in wastewater by natural manganese oxide minerals,which have strong oxidation capability,is investigated.The reaction process for oxidizing phenol by manganese oxide minerals is simulated.Through measuring the oxidation results by manganese oxide minerals at initial concentrations of 100-1000 mg/L,pH values of 1.0,1.5,2.0,experimental temperatures of 293-333K,and various time periods respectively,and comparing linearity simulations of the pseudo-first and the pseudo-second order equations,it is indicated that the correlation coefficient of linearity simulation of the pseudo-second order model is higher than that of the pseudo-first order model,so this oxidation reaction can be simulated by the pseudo-second order equation.The Arrhenius reaction activation energy of 11.62 kJ/mol indicated that this reaction is not obviously influenced by the experimental temperature and it is a diffusion-controlled reaction. |
