Abstract

Abstract: In this paper, Fe₃O₄ nano microspheres were prepared by precipitation method, and then polypyrrole and Fe₃O₄ were combined under the action of ultrasonic to form polypyrrole based magnetic nanocomposites. The composites were characterized by XRD, FTIR, SEM, TEM and magnetic properties. The experimental results show that polypyrrole and Fe₃O₄ nano microspheres have been successfully compounded, and the particle size is about 200 nm, producing composites with saturation magnetization of 48 emu/g. The further experiment was carried out to study the cyclic adsorption of copper ion with composite materials as adsorbent. The adsorption efficiency of the first cycle was 94.50%, and after five cycles of adsorption, the adsorption efficiency was 88.25%. At the same time, the composite has strong magnetic properties, so that the whole cyclic adsorption process can be carried out through magnetic adsorption, which is simple, time-saving and labor-saving. Therefore, the composite has a good application prospect as a circulating adsorbent.

Key words: magnetic Fe₃O₄, polypyrrole, composite material, adsorption property
