| 摘 要： | 研究了不同条件下亚甲基蓝在普通锐钛型二氧化钛上的吸附及对其超声催化降解的影响。实验结果表明:亚甲基蓝的吸附受溶液酸碱度的影响最大,酸性条件下吸附很小,随pH的增加,吸附量呈大幅上升的趋势,降解率也上升,温度升高,吸附量和降解率下降;初始浓度增加,降解率下降。TiO2的最佳用量为1．0/L。

| Abstract: | Different affecting factors were studied about the adsorption of methylene blue on TiO2 and its effects on sonocatalytic degradation. The results indicated that the adsorption of methylene blue on TiO2 was obviously influenced by pH of the solution. A small amount of methylene blue being adsorbed on the catalyst has been detected in acid solution and adsorption increased rapidly as alkalinity increased; The ratios of adsorption and degradation decreased as both the temperature and initial dye concentration increased; the appropriate dosage of TiO2 was 1.0g/L. |
