Synthesis of Zinc Sulfide Nanoparticles by Chemical Coprecipitation Method and its Bactericidal Activity Application
A particle of zinc sulfide (ZnS) was synthesized by the chemical coprecipitation method using zinc sulfate heptahydrate (ZnSO4), ammonium sulfate (NH4) 2SO4 as a reactant, and thiourea as a stabilizer and capping agent. The optioned product characterized by electron dispersive X-ray spectroscopy tha...

| description | A particle of zinc sulfide (ZnS) was synthesized by the chemical coprecipitation method using zinc
sulfate heptahydrate (ZnSO4), ammonium sulfate (NH4)
2SO4 as a reactant, and thiourea as a stabilizer
and capping agent. The optioned product characterized by electron dispersive X-ray spectroscopy
that exhibits the presence of Zn and S elements. The average particle size of the ZnS nanoparticles
determined using X-ray diffraction is about 4.9 nm. The ultraviolet–visible spectroscopy showed the
blue shift in wavelength and the band gap was 4.33 eV, the surface morphology of the synthesized
ZnS nanoparticles powder was studied by scan electron microscopy which was showed the irregular
and some spherical shapes of ZnS in a nanosized range. The Fourier-transform infrared spectroscopy
observed an absorption peck at 657.73 and 613.36 cm−1 that were assigned to the stretching mods
of the Zn-S band. The different amounts of ZnS nanoparticle were applied as bactericidal against
Staphylococcus aureus by disk diffusion method. It displayed activity against S. aureus bacteria, which
was carried out in the absence of irradiation. |
