Preparation of C-TiO2 composite with assistance of microcrystalline cellulose and its adsorption properties for Cd2+

  • 摘要: 采用溶胶-凝胶法,利用微晶纤维素(CMC)辅助制备了C-TiO2复合材料,并对其进行了结构、组成和形貌的分析。XRD分析结果表明,所制备的C-TiO2复合材料样品为具有较高的结晶度的锐钛矿相TiO2和石墨碳的复合材料; SEM、TEM和XPS分析表明,CMC在C-TiO2复合材料的制备中起到双重作用:既是复合材料中C的前驱体,同时会增大所制备的TiO2的分散程度。同时,利用Cd2+考察了C-TiO2复合材料样品对重金属离子的吸附能力。实验表明,与未添加CMC的TiO2相比,所制备的C-TiO2复合材料对重金属离子具有很好的吸附性能,吸附量达到37.15 mgg-1,是未添加CMC的平衡吸附量(17.32 mgg-1)的214.5%。C-TiO2优异的吸附性能将使其在Cd2+的污水处理上具有很好的应用前景。
    Abstract: C-TiO2 composites were successfully prepared via sol-gel method with assistance of microcrystalline cellulose(CMC). The structure, components and morphology of C-TiO2 composites have been fully studied. The results of XRD show that:C-TiO2 composite has the structure of anatase with high crystallinity; the analyses of SEM, TEM and XPS give the evidence that cellulose has dual effects on the preparation of the C-TiO2 composite:it is the precursor of carbon, and it also works as dispersant which makes TiO2 well dispersive. The adsorption experiments of Cd2+ has been carried out to evaluate the adsorption property by the C-TiO2 composite. Compared with the TiO2 prepared without cellulose, C-TiO2 composite has high adsorption. The adsorption amount of Cd2+ reaches 37.15 mgg-1, which is 214.5% as higher as that without cellulose. At the same time, C-TiO2 composite has excellent adsorption efficiency, which makes C-TiO2 a good candidate for water treatment.
