Biosynthesis of Green Silver Nanoparticles and Its UV-Vis Characterization
In a recent time, silver nanoparticles (AgNPs) have attracted a lot of attention from researchers because of their special properties. In this paper green silver nanoparticles (AgNP) were synthetized from 2, 4 and 8 % w/v orange peel extracts. The synthesis was done by the process of chemical reduction in the presence of 1 mM silver nitrate (AgNO3) solution at 23 °C at 400 rpm for 6 hours. Orange peel extracts were used as capping agent to reduce 1mM solution to silver nanoparticles. The biosynthesized AgNPs were characterized by UVVis spectroscopy in the wavelength range from 300 to 600 nm with maximum of absorption at 460 nm. The results have shown that by increasing the concentration of peel extract increase the formation of silver nanoparticles. The advantage of this green method of synthesis is the use of fruit waste to create new valuable materials with potential antibacterial activity.
