摘      要：The authors investigated the catalytic activity of TiO2 for methylene blue（MB） degradation under solar *** reaction parameters such as reaction time,TiO2 content,temperature,pH,MB concentration and light irradiation were in ***,the experimental data was analyzed to investigate the adsorption order and adsorption *** results indicate that the optimum conditions for the removal of MB are a TiO2 content of 0.5 g/L,0.50 mg/L MB solution,a temperature of 30 ℃ and reaction time of 60 *** was found that the amount of MB removal was decreased when the pH and temperature *** suggests that the removal process is ***,the solar light irradiation plays a vital role in enhancing the removal amount of *** the dark reaction,the ability of TiO2 to remove MB was increased when the pH *** kinetics studies confirm that the adsorption of MB is the *** the adsorption model was fitted with the Freundlich isotherm.
