A Green Chemistry Approach to the Synthesis and Characterization of Silver Nanoparticles

Traditional synthesis of nanoparticles employed only physical and chemical methods. More often the chemical synthesis methods employed in this production usually makes presence and absorbance of some toxic chemical substance on their surface and this may result in an adverse effect in several medical and other applications. No such adverse effects appear if they are biosynthesized using technology of green synthesis. This paper emphasizes on the synthesis and characterization of silver nanoparticles that can be applied in cleaning up of an environment such as an anti-biofouling compound synthesis by an environmentally friendly green synthesis technique. Aqueous extracts from the leaves of plant S. siamea were used as the reducing agents to produce the nanoparticles. UV-Visible spectroscopy monitored the synthesis of colloidal silver Nanoparticles and it showed a peak at 429 nm corresponding to the Plasmon absorbance of the silver nanoparticles. SEM analysis and FTIR and EDS XRD were employed to characterize other aspects like that of the size and shape.
