| 摘 要： | 采用水热法制备了TiO2纳米管,借助X射线衍射(XRD)、透射电镜(TEM)对产物进行了表征。以亚甲基蓝溶液为体系,考察了TiO2纳米管的吸附性能。结果表明:TiO2纳米管为锐钛矿相,管径小、管形均匀。黑暗条件下TiO2纳米管对亚甲基蓝具有优异的吸附活性,30 min可达到吸附平衡,吸附量达38.3mg/g,最佳吸附质量比为w(MB):w(TiO2)≈0.075。

| Abstract: | TiO2 nanotubes were prepared by hydrothermal synthesis,and the products were characterized by X-ray diffraction（XRD） and transmission electron microscope（TEM）.The adsorption of TiO2 nanotubes obtained was investigated in a methylene blue（MB） aqua system.The results showed that TiO2 nanotubes was anatase phase with smaller diameter and evenly shape.The TiO2 nanotubes had high adsorption activity for methylene blue in the dark,whose adsorption equilibrium was reached within 30min.The adsorbility capacities of MB could reach 38.3mg/g and the best adsorption mass ratio of MB/TiO2 was about 0.075. |
