The preparation of bismuth modified ensembles of gold nanoelectrodes (Bi-NEE) is described for the first time. Bi-NEEs are characterized and successfully applied for anodic stripping voltammetric measurement of trace Pb(II). Optimization of the experimental parameters provided low detection limits of 60 ng L−1 and 30 ng L−1 by using in-situ and ex-situ bismuth film deposition, respectively, after a 3 min accumulation step.

Abstract

The preparation of bismuth modified ensembles of gold nanoelectrodes (Bi-NEE) is described for the first time. Bi-NEEs are characterized and successfully applied for anodic stripping voltammetric measurement of trace Pb(II). Optimization of the experimental parameters provided low detection limits of 60 ng L−1 and 30 ng L−1 by using in-situ and ex-situ bismuth film deposition, respectively, after a 3 min accumulation step.
