以１２５ Ｗ 高 压汞灯 为光源，以 Ｔｉ Ｏ２ 为 催化剂，对 不同初 始浓度的 苯酚水溶 液进 行了 光催化降解 实验； 同时，考 察了不同 溶液ｐ Ｈ 值时的 光催 化行 为． 根据 实验 结果， 提出 了与 文献 报 道不同的 Ｔｉ Ｏ２ 光催 化降解苯 酚的零级 反应动 力学模型
A 125 W high pressure mercury lamp was used as a light source and Ti O2 was used as a catalyst to photocatalyze degradation of phenol aqueous solutions with different initial concentrations. Meanwhile, the photocatalytic activities at different pH values were investigated. According to the experimental results, a new zero-order reaction kinetic model of photocatalytic degradation of phenol with different Ti O2
