Abstract
The present disclosure provides an efficient and stable magnetic nanofiber membrane and a preparation method and use thereof, and belongs to the technical field of composites. The preparation method includes the following steps: dissolving polyacrylonitrile or polystyrene, nZVI particles, and n-octyltrimethylammonium bromide in N,N-dimethylformamide, and mixing uniformly to obtain a spinning solution; subjecting the spinning solution to electrospinning; and vacuum-drying a resulting fiber membrane to obtain the efficient and stable magnetic nanofiber membrane. In the present disclosure, the magnetic nanofiber membrane has a high specific surface area, a desirable porosity, an excellent mechanical strength, and satisfactory magnetic properties. The membrane effectively exerts a synergistic effect of the nZVI particles and an organic polymer material carrier, avoids easy oxidation of a catalyst surface and easy particle agglomeration, enhances a catalytic activity of the magnetic nanofiber membrane, and improves an efficiency in organic wastewater treatment.
