Nickel ferrite/carbon nanotubes (NF/MWNTs) composites were prepared by impregnation method. The composition, structure, morphology, magnetic property, and adsorption property of the samples were characterized by XRD, SEM, TEM, VSM, UV-Vis, etc. The results indicate that the NF/MWNTs composites not only keep the good adsorption performance of carbon nanotubes, but also have nice loading factor for nickel ferrite and excellent magnetic property. The adsorption behavior of the NF/MWNTs composite with m(NF)/m(MWNTs) of 1 on methylene blue solution is in accord with Langmuir model and Freundlich model. The maximum adsorption capacity of the composite can reach 18.87 mg . g(-1). Meanwhile, the temperature and pH value have positive correlation with the discoloration rate of methylene blue solution. In addition, the NF/MWNTs composites can be recovered easily with magnetism and can be activated simply and conveniently for reuse.
