纳米TiO_2光催化降解亚甲基蓝的研究

A study on the photocatalytic oxidation of methylene blue using adherent TiO_2 catalysts

在封闭的光催化反应器中,以紫外光为光源,γ-Al2O3为载体,纳米TiO2为催化剂,进行了亚甲基蓝溶液降解脱色研究,分别从催化剂用量、反应初始浓度、光源强度及H2O2的添加量等方面考查了亚甲基蓝的降解率。结果表明,能够有效地完成亚甲基蓝等有机物降解脱色和降解,降解率可达95%以上。

The photocatalytic degradation of methylene blue in violet irradiation with adherent TiO2 catalysts was investigated intensively.The quality and quantity examination of the decolorization effect and testing of the organic methylene blue show that violet reactor with adherent TiO2 catalysts can decolorize methylene blue and remove organic carbon effectively.
