In this study, Iron oxide–alumina mixed nanocomposite fiber was prepared by electrospinning method and its performance was evaluated as a heavy metal ion adsorbent.

The electrospun nanofiber was sintered at 1000°C for converting it to pure oxide form for further application as adsorbent. Iron oxide–alumina mixed nanocomposite fiber was characterized by UV–vis-DRS, IR, SEM–EDX, TEM, BET and TGA–DTA analytical techniques. Batch adsorption experiments were carried out to study the sorption behavior of Cu2+, Pb2+, Ni2+ and Hg2+ ions as a function of initial concentration, contact time and pH. The removal percentage was in the order of Cu2+<Pb2+<Ni2+<Hg2+.
