Polyvinylimidazole (PVI)-grafted iron oxide nanoparticles (PVIgMNP) were prepared by grafting of telomere of PVI on the iron oxide nanoparticles. Different metal ions (Cu 2+ , Zn 2+ , Cr 2+ , Ni 2+ ) ions were chelated on polyvinylimidazole-grafted iron oxide nanoparticles, and then the metal-chelat...
