摘要
纳米材料作为一种新兴的材料近年来越来越多地用于重金属离子的去除,而静电纺丝技术是制备纳米纤维最有效最直接的方法。静电纺丝纳米纤维具有纤维直径小、比表面积大、孔隙率高、吸附性能强等优点。主要介绍了静电纺丝纳米纤维膜近年来在处理重金属离子方面的一些研究进展,通过对纳米纤维进行官能团改性、加入无机物等方法制备复合纳米纤维膜已经成为近几年研究的热点。
As a kind of new material, nanometer materials are more and more used in removing heavy metal ions. And electrospinning has recently emerged as one of the most important techniques for preparing nanofibrous membranes, because of the interesting properties of nanofibers, which include submicron to nanometer diameters, a large surface area per unit mass, high porosity, high gas permeability, and small interfibrous-pore size. The research progress on electrospinning nanofibrous membranes in removing heavy metal ions are introduced. The fibre.membrane with modified functional groups or inorganic substances etal has become a research hotspot in recent years.
