Abstract

This project is focuses on novel, cost effective and simple plant mediated synthesis of silver nanoparticles (Ag-NPs) using leaf extract of Albizia procera. The optical, structural and physical properties of green synthesized Ag-NPs have been investigated by UV-Visible spectroscopy, X-ray Diffraction (XRD) and Atomic Force Microscopy (AFM), respectively. Prepared Ag-NPs are spherical in shape and crystalline in nature with an average size of 6.18 nm. Ag-NPs have showed promising potential in removal of organic pollutant methylene blue (MB) dye. Careful investigation on the removal of dye as a function of contact time, UV light and exposure time, dose of nanoparticles, temperature and pH have also been carried out. Moreover, Ag-NPs exhibit outstanding antibacterial activities against gram negative Escherichia coli (E. coli) and gram positive Staphylococcus aureus (S. aureus) bacterial pathogens.
