研究了TiO2光催化（波长为365 nm）在水溶液悬浮液中对亚甲基蓝的降解（氧化）。该反应符合Langmuir吸附等温线，且速率与pH曲线随酸性溶液的pH值呈线性增长，在pH值约为6.9时达到最大值。
The degradation (oxidation) of methylene blue assisted by TiO2 photocatalysis (with an irradiation wavelength of 365 nm) was investigated in aqueous suspension. The rate constants for this heterogeneous photocatalysis were evaluated as a function of the concentration of the dye, the amount of TiO2 and the pH. The reaction is found to conform to a Langmuir adsorption isotherm and the rate vs. pH profile exhibits a linear increase with pH in acidic solutions with a maximum at around pH 6.9.
