以环境中常见的多环芳烃污染物苯并[ɑ]芘（Bap）为研究对象，探讨了类Fenton试剂、活化过硫酸钠、高锰酸钾在不同条件下对水中Bap的去除效果以及动力学规律。结果表明，类Fenton试剂氧化Bap的效果最好，去除效率达90.3%；其次是活化过硫酸钠，去除率为86.9%；高锰酸钾对Bap的去除率为76.7%。3种氧化剂氧化Bap的反应过程均符合一级反应动力学规律。根据阿伦尼乌斯方程，做出反应速率常数与温度的关系曲线，计算得到3种氧化剂氧化Bap的表观活化能，其数值均大于一般化学反应，表明该氧化反应比一般的化学反应慢。
In order to investigate the removal ability of polycyclic aromatic hydrocarbons, the most widely existent benzopyrene（Bap）is chosen as the target pollutant. Different oxidants like the modified Fenton reagent, activated persulfate and permanganate are evaluated for removal of Bap. from drinking water and the kinetic law of Bap Oxidation is studied. The result shows that modified Fenton reagent has the highest Bap removal rate (90.3%). The removal of Bap by activated persulfate reaches 86.9%. Permanganate can remove 76.7% of Bap. The removal of Bap with these oxidants obeys the first-order kinetics and the curve between the reaction rate constant and temperature is shown using Arrhenius. Meanwhile, the reaction activation energies of different oxidants are obtained, and their chemical reaction rates are slightly lower than that of the common chemical reaction, which reveals that the Bap oxidation by these oxidants is not feasible.
