Polymeric membranes, highlighting those functionalized with nanoparticles of metal oxides, have emerged as an innovation to the processes for water treatment, since they have a high performance and because they present synergic effect between both components, these membranes can achieved excellent mechanical, morphological and chemical properties for the removal of contaminants1. In this sense, ZnO has been widely used for its excellent antibacterial and photocatalytic activity, allowing the elimination of pathogenic agents, organic and inorganic contaminants2; said properties are increased or improved when the materials are arranged on a nanometric scale. On the other hand, acrylonitrile-butadiene-styrene (ABS) is a copolymer with high demand due mainly to its excellent thermal, chemical and mechanical properties.3 However, to date it has been used in a limited way to prepare fibrous membranes. 4 Thus, the objective of the present work is to develop membranes consisting of sub-micron fibers of ABS and zinc oxide nanoparticles, by means of the coaxial electrospinning technique, which would allow obtaining fibers with a ZnO-rich surface in order to improve removal/reduction of metal ions.
