▎ 摘　　要

Zinc ferrite reduced graphene oxide (ZF-rGO) magnetic adsorbent was prepared by a facile one-pot solvothermal method. TEM study suggests that zinc ferrite (ZF) nanoparticle is uniformly distributed and firmly anchored on the reduced graphene oxide (rGO) with a high density. The magnetic and adsorptive experiments' results demonstrate that both of the ZF and ZF-rGO show enhanced magnetic properties and the ZF-rGO composite material is an ideal adsorbent candidate for removing methylene blue (MB) in water due to its high adsorption capacity and easy and effective separable property based on its outstanding magnetic property. The adsorption behavior follows a pseudo-second-order kinetic model. (C) 2013 Elsevier B.V. All rights reserved.
