Adsorption Properties of Magnetic CoFe2O4 Based Spinel Nanoparticles

This review discusses different techniques for synthesis of magnetic cobalt spinel adsorbent. In this review, adsorption capacity together with magnetic properties of CoFe2O4 nanoparticles, CoFe2O4 nanocomposites Me-doped CoFe2O4 have been presented. The corresponding adsorption isotherms are analyzed. The data of adsorption were fited well with Langmuir model—monomolecular layer is formed. Cobalt ferrite exhibits high adsorption capacity for organic and inorganic model pollutants. Magnetic adsorbent remove of the pollutant in the first cycle and after recycling.
