摘要：
Herein, TiO2 was prepared by the hydrolysis method in critic acid (with both carboxyl and hydroxyl groups) solution firstly. And then, the as-prepared TiO2 was calcined at 50, 150, 250, 350, and 450 degrees C, respectively, in order to investigate the effects of the calcination temperature on the physicochemical property and the adsorption performance of TiO2. The adsorption performance of the prepared TiO2 samples for cationic dye-Methylene Blue (MB) was also studied. The results indicated that high calcination temperature can destroy the organic moieties on the TiO2 samples and further influence the adsorption performance of TiO2 for the removal of cationic dye-MB.
