Copper ferrite immobilized on graphene-like carbon nitride nanosheets was successfully prepared and characterized by X-ray, Infrared and ultraviolet-visible spectroscopy, scanning electron microscopy and thermogravimetric analysis. The obtained material was used as an adsorbent for removing phosphate anions from aqueous media. The influence of adsorption parameters such as pH, initial concentration of phosphate anions, contact time and adsorbent dose on the efficiency of the process was studied. The highest sorption of phosphate ions (>97%) is observed at solution pH-3. A comparative study of the applicability of the Langmuir and Freundlich adsorption models for describing experimental phosphate adsorption isotherms was carried out. The adsorbent can be easily removed from the aqueous solution by an external magnet after application and reused for 5 cycles while maintaining high adsorption efficiency.
