    Synthesis and characterization of zinc sulphide nanoparticles from garlic and onion extract using the biosynthesis method
    (Busitema University, 2023) Musene Benjamen
    ZnS nanoparticles were synthesized using garlic and onion extract. The green synthesis method was used since it was ecofriendly in that toxic gases and high temperatures are not involved. Additionally, this method is also cheap. Garlic and onion gloves were obtained from nagongera town council, dried and 10g of each sample was measured and dissolved in 200mls of distilled water. 0.04 moles of zinc nitrate solution were made by dissolving 12g of zinc nitrate in 50mls of water. A solution of sodium sulphide was also made by dissolving 5.2g of sodium sulphide in 50mls of water. The two solutions are then mixed together followed by addition of the extract solution with constant stirring for 60minutes. During nanoparticle formation, there was color change from white to pale yellow for garlic extract and brown to green for onion extract. After the synthesized nanoparticles where dried, that from garlic extract gave 4g while that from onion extract gave 2g. The FTIR machine was used to characterize the nanoparticles and different spectrums were obtained as shown in the report. However, the spectrums showed some peaks above 3000cm-1. This would have come as a result of other phenolic compounds found in garlic.
