摘要

Iron is a crucial trace element in DNA synthesis, oxygen transport and various biological processes. However, iron overdose can result in health issues like liver damage and neurodegenerative disorders. The present study reports a green and eco-friendly route for biosynthesis of lead oxide nanoparticles using Bougainvillea flower extract. The structural and chemical composition of lead oxide was investigated by XRD and XPS methods, respectively. The average diameter size of lead oxide was ~ 400 nm. The lead oxide-modified glassy carbon electrode (GCE) was investigated for electrochemical sensing of iron (III) ions in aqueous solutions. The lead oxide electrodes show a nearly linear increase in peak current density with varying iron concentrations, indicating effective detection capabilities. The lead oxide displayed high sensitivity, selectivity and durability for detecting iron (III) ions with a detection limit of 8.22 mM in the linear detection range of 0-0.1 M. The results highlight oxide-based electrochemical sensors as a promising candidate for real-time detection and quantification of iron (III) ions in aqueous environments.
