Abstract

Current work presents a detailed study on the synthesis of silver nanoparticles (70 ± 5 nm) functionalized with 4-mercaptobenzoic acid and their interaction with divalent ions (Cu2+, Fe2+, Co2+, Ni2+, Pb2+, Mn2+, Zn2+, Sn2+). The study reveals the morphological changes in the nanoparticles due to interaction with Cu2+, resulting in the formation of larger nanoparticle aggregates. The UV-Vis spectra of the pristine and aggregated nanoparticles are also discussed, providing insights into the changes in their optical properties. These nanoparticles are used to detect divalent ions using surface-enhanced Raman spectroscopy with a detection limit of 2.5 × 10–7 M for Cu2+ and also show a linear response within the 10–3 to 10–7 M concentration range. High selectivity for Cu2+, Fe2+, Co2+, Mn2+, and Pb2+ was also detected. The findings of this study could have significant implications in the field of nanomaterials and environmental chemistry, particularly in the detection and removal of heavy metal ions.
