In this study, the biosynthesis and characterization of silver nanoparticles (AgNPs) from orchid tree (Bauhinia variegata) leaf extract were firstly carried out, and then, the usability of AgNPs as a colorimetric sensor for detection of Fe3+ ions in aqueous solutions was evaluated. The characterization studies showed that the synthesized particles were determined to be AgNPs in nanoscale and face-centered cubic structure. Besides, the total phenolic content of B. variegata extract was determined to be 1.826 ± 2.1 mg gallic acid equivalents/g dry leaf. Also, the biosynthesized AgNPs showed a strong surface plasmon resonance (λSPR) around 430 nm and λSPR intensity decreased with the increasing in Fe3+ concentration in aqueous solution. Based on the linear relationship between the change of λSPR intensity and Fe3+ ion concentration, AgNPs can be used for the sensitive and selective detection of Fe3+ ions in aqueous solutions with a linear range of 6-100 μM and a detection limit of 2.08 × 10−6 M.
