In the present study, a novel superparamagnetic nanocomposite composed of magnetite as the core and zeolite coated by glutaraldehyde-crosslinked chitosan as the shell has been successfully synthesized.The synthesis steps include coating silica on the surface of magnetite nanoparticles and conversion of the silica layer into a zeolite layer, coating of chitosan on the surface of the zeolite, and cr...
