摘要
采用偶联剂法在聚丙烯多面球表面固载纳米TiO2,在高压汞灯照射下,以亚甲基蓝染料为研究对象,对光催化氧化亚甲基蓝溶液的反应动力学进行了试验研究,结果表明:负载TiO2薄膜的聚丙烯多面球光催化降解亚甲基蓝溶液的反应表现为一级动力学反应,反应速率遵从多相催化动力学方程——Langmuir-Hinshelwood方程,反应速率常数K为0.2544mg/(L.min),吸附平衡常数KA为0.4474mg-1.L。
The kinetics of photocatalytic oxidation reaction for methylene blue solution was studied by using immobilized nanometer TiO2 photocatalyst under the irradiation of high pressure mercury lamp. The results indicated that the reaction was that of first-order and the velocity of reaction was coincident with multiphase catalytic kinetic equation： Langmuir-Hinshelwood equation. The reaction velocity constant and adsorption equilibrium constant were 0. 2544 mgL^-1 min^-1 and 0. 4474 mg-XL respectively.
