This presentation highlights the one pot synthesis, characterization, and electro-chemical properties of Bismuth nano-particles (BiNPs). Bismuth, in the presence of chloranilic acid (CAA) and bromated ion has been shown to form electroactive absorbable complexes with vanadium (V); allowing for detection of V in trace amounts. In this research BiNPs were used due to their large apparent surface area and their ability to form complexes with V, which was monitored using adsorptive stripping voltammetry (AdSV). The BiNPS were characterized using Energy-dispersive X-ray spectroscopy, Scanning Electron Microscopy, and electrochemical techniques. Introductory findings suggest that the high surface area to volume ratio improves the BiNPs ability to form complexes with V and allows for a lower detection limit at trace amounts. Factors influencing the ADSV performance including solution pH, CAA concentration; preconcentration time will be optimized and discussed. Prospective analytical applications of BiNP electrodes (BiNPEs) in environmental uses will be presented.
