However, these methods are not applicable for the on-site measurements of Pb(II) since the equipment is too bulky and skilled laboratory staff are needed. In this study, coastal water samples were collected from different sites close to two coastal industrial complexes in Korea. Their Pb(II) concentrations were determined using electrodeposited gold nanoparticles (AuNPs) on a disposable screen-printed carbon electrode. Square wave anodic stripping voltammetry was used to enhance the sensitivity of the Pb(II) detection leve...
