Abstract

The present invention relates to a nanostructured composite of polyvinyl alcohol (PVA) nanofibers with strontium hexaferrite nanoparticles (SrM-NPS) distributed therein. Said composite allows removing mixed arsenic in aqueous media. PVA magnetic nanofibers exhibit high surface area, the magnetic anisotropy of shape along the longitudinal axis with novel modes of magnetization reversal, and a distinctive arsenic adsorption capacity, controlling the density of SrM-NPs below the limit of percolation. The dispersed system of SrM-NPs in the polymeric matrix promotes excellent physical-chemical and magnetic properties, thermal stability, high values ??of remanence magnetization normalized for saturation magnetization, Mr/Ms, the coercive field, Hc, a small value of the switching field distribution, SFD, a high energy product, and (BH)max. Further, the present invention has a wide spectrum of technological applications, producing magnetic nanofibers at relatively low costs using a continuous electrospinning process in arsenic adsorption and fixation. Finally, it exhibits physical-chemical properties, making it economical for remediating the environment in places of arsenic contamination.
