Mechanism of interaction of chitosan with cobalt ferrite during synthesis by mechanochemical activation

A nanosized chitosan–cobalt ferrite biocomposite has been prepared by mechanochemical synthesis. The synthesized biocomposite is investigated using atomic force analysis, X-ray diffraction analysis, and infrared spectroscopy. The formation of the biocomposite depends on the amount of chitosan in the reaction medium. A mechanism of the formation of the chitosan–cobalt ferrite biocomposite is suggested. The biocomposite is designed for reducing the toxicity of magnetic nanoferrimagnetics upon their use as drug carriers, adsorbents of toxic compounds, etc.
