文摘

Ni, Cu and Zn sulfide nanoparticles (NPs) were synthesized using a simple route. The NPs were citrate stabilized. They were characterized by UV–vis, ζ potentials, TEM and Raman spectroscopic techniques. They having sensing aptitude for heavy metals Hg2 +, Cd2 + and Pb2 +. NiSNPs are selective sensors for Hg2 +.
