A new one-pot reverse microemulsion synthesis of ZnS nanoparticle using olive oil as organic solvent and surfactant and their application in remove heavy metal ions

In current study, ZnS nanoparticles were successfully synthesized with the aid of C2H5NS and Zn(NO3)(2)center dot 6H(2)O as the starting reagents in the presence of olive oil as surfactant and oil (organic solvent). Besides, the effects of preparation parameters such as magnetic stirring time and its rpm on the morphology of ZnS nanoparticles, removal of heavy metals (Hg+2, Pb+2) were studied by SEM images and batch adsorption mode. ZnS nanoparticles are synthesized by this method have more efficiency for remove heavy metal because of their modified surface (with olive oil).The as-synthesized products were characterized by several technics such as powder X-ray diffraction, scanning electronic microscopy, spectra energy dispersive analysis of X-ray (EDS), and ultraviolet-visible (UV-Vis) technic.
