Abstract
We introduce the synthesis and electrochemical application of a glutathione functionalized magnetic nanocomposite (GSH@Fe3O4) for the development of a simple, stable and selective sensor for heavy metal ion detection in real-life samples for the first time. The monitoring method is based on electrochemical preconcentration/reduction of metal ions onto a GSH@Fe3O4 modified magnetic glassy carbon electrode, followed by subsequent anodic stripping. This method allows the detection of Pb2+ and Cd2+ ions with high sensitivity (calculated detection limits of 0.182 μgL−1 and 0.172 μgL−1), low cost, and great convenience in operation and was tested for different water samples. The results infer that the GSH@Fe3O4 nanocomposite can be an alternative candidate for practical applications in electrochemical detection of metal ions.
