Abstract

The zinc sulphide nanoparticles were synthesized by simple aqueous chemical reaction of zinc chloride and sodium sulphide in aqueous solution. The main advantage of the ZnS nanoparticles of diameter 29 nm is that the sample is prepared by using of non-toxic precursors in a cost effective and eco-friendly way. The structural, morphological and chemical composition of the nanoparticles have been investigated by X-Ray Diffraction(XRD),Scanning Electron Microscopy(SEM) with energy dispersion X-ray fluorescence spectroscopy (EDAX) and Fourier transform infrared (FTIR) spectroscopy. The antimicrobial effects of the zinc sulphide (ZnS) nanocrystals were studied by well diffusion technique against twelve pathogenic bacterial strains. ZnS showed antimicrobial activity against both gram positive and gram negative strains except Shigella sonnei.

Keywords: zinc sulfide, nanoparticles, aqueous chemical synthesis, antimicrobial.
