Silver nanoparticles (AgNPs) were successfully synthesized via a bottom-up approach by using aqueous extract of lantana camara (LC) leaves as reducing and stabilizing agent. Characterization studies were done using UV-Vis spectroscopy and Fourier Transform Infrared Spectroscopy (FTIR). The average size, morphology and shape of the nanoparticles were determined by Scanning Electron Microscopy (SEM) and Dynamic Light Scattering (DLS). A light brown color indicated the synthesis of AgNPs, caused by a surface plasmon resonance (SPR) peak at 460 nm. The silver nanoparticles were used to detect mercury (Hg2+) ions. A color change of the AgNPs solution from light brown to cloudy white due to oxidation of Ag0 to Ag+1 ions was observed. A good selectivity of the AgNPs towards mercury ions in water has been obtained. This method was found to be simple and rapid for detection of Hg2+ ions and demonstrated a potential to be used in environmental colorimetric sensor applications.
