Urchin-like Ni-P microstructures: facile synthesis, properties and application in the fast removal of heavy-metal ions

Urchin-like Ni-P microstructures with room-temperature magnetism have been successfully synthesized via a simple water-DMF solvothermal route. The as-obtained product exhibits good capacity to rapidly remove heavy-metal ions such as Cd(2+) and Pb(2+) ions from water and can be easily recycled owing to their magnetism.
