摘要：

Magnetite (Fe3O4) and Fe3O4 coated with cetyltrimethylammonium bromide (CTAB) were successfully synthesized by simple wet-chemical method. The results show that the products were Fe3O4 nanoparticles. The saturation magnetization and BET method reveal these nanoparticles exhibited superparamagnetic behavior with high surface area. So, it is a very potential application for using as adsorbents for anionic dye Congo red (CR) removal. Its adsorption capacity, calculated by Langmuir isotherm, is 93.46 mg/g. Furthermore, the pseudo-second order model and intra-particle diffusion model (IPD) were also investigated. (C) 2017 Elsevier B.V. All rights reserved.
