- Abstract:
- Green synthesis of silver nanoparticles (AgNPs) has been produced by mixing silver nitrate solution with leaf aqueous extracts of three Tunisian plants namely Basil, Eucalypltus and Geranium as a reducing and stabilizing agent for AgNPs. After only 10 min of reaction, the light yellow color of the plant leaf extract was changed to brown due to the reduction of silver ions to AgNPs, under ambient conditions. The formation of biosynthesized AgNPs was monitored by UV-Visible spectroscopy which revealed an absorption peak at 400 nm. X- Ray Diffraction (XRD) was used to confirm the average particle size of AgNPs which were found to be 40, 50 and 30 nm using Basil, Eucalypltus and Geranium leaves aqueous extracts, respectively. Fourier transform infrared (FTIR) spectrum confirmed the possible interaction between silver nanoparticles and capping agents.
