| 摘 要： | 对初始浓度、pH值、温度、TiO_2用量及紫外光强对亚甲基蓝光催化降解反应的影响进行了研究,结果表明亚甲基蓝可以被很快地降解,尤其是在较低浓度下更为有效。在反应中,存在一个pH值,提高温度、TiO_2用量及光强均对提高反应速率有益。温度与初始浓度的影响可以同时入反应动力学方程。

| Abstract: | Effects of initial concentration of methylene blue,pH value of solution,reaction temperature,loading of titanium dioxide and UV light intensity on photodegradation of methylene blue have been investigated.Mechanisms of the interactions between effecting factors and degradation of methylene blue were explained.Kinetics for photocatalytic degradation mainly involving initial concentration and temperature were also discussed.The results indicated that methylene blue could be degradated efficiently under the approximate conditions. |
