Silver (Ag) nanoparticles have recently been widely applied due to its high surface plasmon resonance (SPR) properties compared to other metals. In this present work, Ag nanoparticles were prepared through a green synthesis technique that uses sentul peel extracts as a reducing agent. Ag nanoparticles were prepared by reacting AgNO3 and the extract at the volume ratios of 4:1, 3:2, and 1:1. These solutions were heated at 80°C for 30 minutes to form colloidal silver nanoparticles. The optical properties of Ag nanoparticles were characterized using UV-Vis and FTIR spectroscopy. Furthermore, Ag nanoparticles were tested as an indicator of mercury metal detection in term of colorimetric. The UV-Vis absorbance peak of Ag nanoparticles was obtained at wavelengths of 409 nm, 408 nm, and 402 nm. The FTIR spectrum showed the presence of four functional groups, namely, C≡C, C=O, HC≡CH, and O-H. The optimum sample of Ag nanoparticles in the detection of metallic mercury is the 4:1 sample because it shows a significant colour change.
