Abstract

Cellulose nanocrystals/chitosan/polyvinyl alcohol (CNC/CS/PVA) composite nanofibrous films were prepared while using an electrospinning technique and successfully thiol-functionalized. Then, the modified films were used for the sorption-desorption of Cu(II) and Pb(II) ions. Subsequently, the adsorption capacity of the films was investigated by changing the CNC loading level, solution pH, and adsorption time. Results showed that the adsorption of metal ions by the films was the best with CNC loading level of 5 wt %, pH of 6, and adsorption time of 4 h. The adsorption behavior of the films was agreed with the Freundlich model. The adsorption equation of metal ions could be described while using a pseudo-second order model. Based on the Langmuir model, the maximum adsorption capacities of Cu(II) and Pb(II) ions were estimated to be 484.06 and 323.49 mg/g, respectively. The Cu(II) and Pb(II) ions adsorption efficiencies of the films after 4 adsorption-desorption cycles were 90.58% and 90.21%, respectively. This study may provide a feasible approach for the application of functional CNC/CS/PVA nanofibrous films in the treatment of water.

摘要

采用静电纺丝技术制备了纤维素纳米晶体/壳聚糖/聚乙烯醇（CNC/CS/PVA）复合纳米纤维膜，并成功进行了硫醇功能化。然后，将改性后的膜用于铜（II）和铅（II）离子的吸附-解吸。随后，通过改变CNC负载量、溶液pH值和吸附时间来研究膜的吸附容量。结果表明，当CNC负载量为5 wt%、pH值为6、吸附时间为4 h时，膜对金属离子的吸附效果最佳。膜的吸附行为符合Freundlich模型。金属离子的吸附方程可以用准二级模型来描述。基于Langmuir模型，估计铜（II）和铅（II）离子的最大吸附容量分别为484.06和323.49 mg/g。经过4次吸附-解吸循环后，膜对铜（II）和铅（II）离子的吸附效率分别为90.58%和90.21%。该研究可为功能化CNC/CS/PVA纳米纤维膜在水处理中的应用提供一种可行的方法。
