Abstract :The present work describes the successful preparation of iron oxide nanoparticles insert ignore into journalissuearticles values(NSB1); stabilized with 4-insert ignore into journalissuearticles values(insert ignore into journalissuearticles values(2-hydroxybenzylidene);amino);benzoic acid. The characterization has been achieved through ultraviolet visible insert ignore into journalissuearticles values(UV-Vis);, fourier transform infra-red insert ignore into journalissuearticles values(FTIR); spectroscopy and scanning electron microscopy insert ignore into journalissuearticles values(SEM); with electron dispersive X-ray elemental analysis insert ignore into journalissuearticles values(EDX);. These magnetic nanoparticles have exhibited significant chemosensing properties in the aqueous media to screen Cr3+, Cd2+, Li+, Co2+, Al3+, Pb2+, Ni2+ and Sr2+ ions. However, lead insert ignore into journalissuearticles values(Pb2+); ions have shown the highest selectivity as compared to other metal ions without any interference in the competitive ion study. The detection limit of Pb2+ ions was found to be 1.7 µM by this nanosensor. The binding ratio and stoichiometry was found to be 1:1 as measured by Job’s plot. The binding strength was also computed through Benesei-Hildebrand equation.
