Synthesis, Characterization and Size Evaluation of Biosynthesized Silver Nanoparticles by UV–Vis Spectroscopy

Mie-Gans (MG) fitting model theoretical utilizing the phenomena of scattering light to determine morphologies, shape, and size metallic nanoparticles in solution. In present work, average radius biosynthesized silver (AgNPs) was evaluated based on their Ultraviolet-visible (UV-Vis) spectra by MG for spherical non-spherical particles. Biosynthesis AgNPs using Lemon (Citrus Limon) leaves extract as a reducing agent Gum Acacia capping stabilizing studied various concentrations Citrus Limon extract. The investigation structural optical properties carried out synthesized samples X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-Vis spectroscopy. XRD confirmed structure revealed that these face-centered cubic (fcc). FTIR measurements indicate presence citric acid leaf which is responsible bioreduced AgNPs. determined surface plasmon resonance (SPR) AgNPs; peaks resonances appear at 436-461nm range. evaluations show most were shape with an range 39-47nm. Moreover, this allows estimation fraction nonspherical aggregated These unique characteristics have made them applicable large number fields like water treatment, biomedical, energy science, catalysis, etc.
