Abstract :
In this work, silver nanoparticles were synthesized from silver nitrate using combretum micranthum leaves extract as a reducing and capping agent. The optical characterization through UV visible spectroscopy revelated a characteristic peak of surface plasmon resonance at 425 nm, while the particle size calculations based on the Mie diffusion theory indicated sizes ranging from 32.5 nm to 44.5 nm. The effects of different reaction parameters including the initial concentration of the precursor and the percentage of the leaves extract, were analyzed. The optimal conditions for the synthesis at room temperature are 0.5 g/L and 7.5 mM, respectively, for the plant extract s weight concentration and the precursor s initial concentration. © 2022 by SPC (Sami Publishing Company), Asian Journal of Nanoscience and Materials, Reproduction is permitted for noncommercial purposes.
