ABSTRACT
In this study, chitosan/poly(vinyl alcohol) (CS/PVA) 50/50 nanofiber membranes were fabricated by the electrospinning technique. These membranes were subjected to a thermal treatment to achieve water stability. Membrane morphology was characterized by FE-SEM and its thermal properties by modulated DSC. Preliminary tests of AS(V) adsorption for concentrations between 0.1 and 5 mg/L were evaluated using HG-AAS. These membranes adsorbed more than 80% of the As(V) in aqueous solution, regardless of the starting concentration and in a less than 30 min. The results obtained agree with previous studies reported in literature for chitosan-based adsorbents.
