摘　　要：研究CuO/γ-Al2O3非均相过氧化氢催化氧化苯酚废水的各种影响因素与动力学规律,结果表明：（1）反应存在最佳pH及过氧化氢加入量（即pH为45、过氧化氢加入量为0.097 1mol/L）;温度对苯酚转化速率影响很大,温度升高,苯酚转化速率加快。（2）动力学研究得到CuO/γ-Al2O3非均相过氧化氢催化氧化体系的模型方程,同时得到该反应的活化能为91.84kJ/mol。The various factors and dynamics in heterogeneous CuO/γ-Al2O3 hydrogen peroxide catalytic oxidation were investigated by using phenol as target organic.The results showed that there was an optimum pH（4-5）and optimal H2O2concentration（0.097 1mol/L）in the catalytic oxidation reaction.The oxidation temperature had great influence on reaction rate,which accelerated the reaction rate by the increase of the temperature.The kinetics model equation in catalytic oxidation system with heterogeneous CuO/γ-Al2O3 catalysts was acquired.The activation energy（91.84kJ/mol）was calculated meanwhile.
