| 摘 要： | 通过水热法在室温下合成了不同铜含量的介孔SiO2微球(Cu-MSM)。目的在于研究吸附剂量、MB的初始浓度以及吸附时间对Cu-MSM从溶液中移除亚甲基蓝(MB)吸附性能的影响。结果表明,当增加Cu-MSM的量时,MB的去除率会大大提高;掺杂铜的介孔SiO2微球可以通过吸附去除水溶液中的亚甲蓝。最后,简要探讨了亚甲基蓝的吸附机理。

| Abstract: | Mesoporous silica microspheres doped with various amounts of copper (Cu-MSM) were synthesized using a hydrothermal method at room temperature. The aim of the present work is to explore the effect of adsorbent dosage, initial concentration of methylene blue (MB), and contact time on the adsorption performance of Cu-MSM for the removal of MB from aqueous solutions. The results show that the dye removal can be greatly improved by increasing the Cu-MSM dosage. The results also indicate that Cu-MSM can be used for the removal of MB from aqueous solutions by adsorption. Finally, the adsorption mechanism of MB is discussed. |
