Abstract
The influence of the synthesis method (chemical co-precipitation, sol-gel method) on the structure and
morphology of the CoFe2O4 nanoparticles was considered and characterized by X-ray powder diffraction
(XRD), Fourier infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). Crystallite sizes
of CoFe2O4 synthesized by zol-gel and co-precipitation methods range from 9 to 42 nm. The adsorption
property of spinel ferrites in relation to organic dye methylene blue was described. The influence of initial
dye concentration at the adsorption capacity of magnetic spinel nanosorbents was considered. The
adsorption of these dyes is well described by kinetic models of Langmuir. The adsorption isotherms show
that the adsorption efficiency of CoFe2O4 nanoparticles, synthesized by co-precipitation method at 800 °C,
is the highest because it has a larger degree of structure inversion.
