3Y-ZrO2/壳聚糖复合材料的制备及其对氟离子吸附性能研究

The Adsorption Characteristics of Composite of 3Y-ZrO2/Chitosan

  • 摘要: 本研究合成了复合材料3Y-ZrO2/壳聚糖,考察了其吸附水体中氟离子的性能。该复合材料为片状结构,对氟离子的最大吸附量为23.3 mg/g。吸附平衡等温线显示,该材料的吸附过程符合Langmuir模型,属于单层吸附。动力学研究表明,该吸附过程符合拟二级。材料制备过程简单,成本低廉,不易产生污染,在处理实际废水方面具有一定的潜力。

     

    Abstract: The composite of 3Y-ZrO2/chitosan was synthesized and its capacity of fluorinion removal from water was investigated in this study. The morphology of the material was found to be sheet, and its maximum adsorption capacity to fluorinion is 23.3 mg/g. The equilibrium adsorption isotherms fit well to Langmuir model, which indicated fluorinion was adsorbed in monolayer adsorption manner. The results of kinetic studies are found to be described very well by the pseudo-second-order kinetic model. The composite is easy to be prepared and costs lowly. Besides, the composite is environment-friendly.
