This communication demonstrates superparamagnetic nano-sized particles with amagnetic core and a porous carbon shell (thickness of 11 nm), which can remove 97% of Pb2+ ions from an acidic aqueous solution at a Pb2+ ion concentration of 100 mg L-1. It is suggested that a weak electrostatic force of attraction between the heavy metal ions and the nanoparticles and the heavy metal ions adsorption on the mesopore carbon shell contribute most to the superior removal property.
