静电纺丝制备铁(Ⅱ)/聚丙烯腈复合纳米纤维及其应用于吸附铬(Ⅵ)
Preparation of Ferrous/Polyacrylonitrile Composite Nanofibers by Electrostatic Spinning and Its Application for Cr(Ⅵ) Adsorption
摘 要
利用静电纺丝技术制备了铁(Ⅱ)/聚丙烯腈［Fe(Ⅱ)/PAN］复合纳米纤维,用于吸附检测溶液中的铬(Ⅵ)。SEM及BET分析可知,纤维形态结构均匀,直径大约为153 nm,比表面积为14.0 m2·g-1。Fe(Ⅱ)/PAN复合纳米纤维表面携带的PAN…Fe(Ⅱ)(OH)+官能团能快速吸附去除溶液中的铬(Ⅵ),并将其还原为铬(Ⅲ)。根据吸附等温线模型分析,Langmuir模型更适合本体系,最大吸附量为5.40 mg·g-1。在优化的试验条件下,97%的铬(Ⅵ)可被从溶液中去除。

Abstract
Ferrous chloride/polyacrylonitrile composite nanofibers were prepared by electrostatic spinning, and applied to the determination of Cr(Ⅵ) in a solution. As shown by the results of SEM and BET analysis, the composite nanofibers obtained had an uniform morphology and structure and a large specific surface area of 14.0 m2·g-1 with diameters around 153 nm. The functional groups of PAN…Fe(Ⅱ)(OH)+ on the surface of the composite nanofibers behaved to adsorb and remove Cr(Ⅵ) ions from a solution quidkly, in the course of which Cr(Ⅵ) ions were reduced to Cr(Ⅲ). The results of the adsorption isotherm experiment showed that the data fitted well to the Langmuir isotherm model. The maximum amount of adsorption of Cr(Ⅵ) was found to be 54 mg·g-1. Under the maximum condition, 97% of Cr(Ⅵ) in the solution could be removed.
