Abstract:

Multifunctional polyaniline nanofibre/Fe₃O₄ nanoparticle hybrids were synthesized by a simple selfassembly method. The application of the nanocomposite in the adsorption of trace amount of Pb²⁺ in water was investigated. The excellent dispersability of the nanocomposite in water and small size of the subunits ensure its fast adsorption of metal ions in water. The magnetic properties and high chemical stability also endow the nanocomposite with excellent reusability, with the help of acid washing by HNO3 solution.
