Abstract :
White Water lily flower, with the scientific name of Nymphaea Alba in the family of Nymphaeaceae, was collected from North of Iran (Sari, Farahabad) in spring, dried in shade and powdered. The powdered flower material was extracted in 70% (V/V) ethanol. Silver nanoparticles (Ag NPs) were synthesized by the reaction of Water lily flower extraction and silver nitrate solution. The progress of the reaction was monitored using UV-Vis spectra at 300-600 nm. The structure of nanoparticles identified through the FT-IR, TEM and XRD spectrum. UV-Vis spectrophotometric study showed the characteristic peak for Ag NPs at wavelength 420 nm (λmax). The morphology of the samples was analyzed using TEM and the particles formed were characterized to be spherical. TEM micrographs revealed the formation of well-dispersed silver nanoparticles in the average size ranging from 5-30 nm.
