Electroanalytical sensing of selenium(iv) utilising screen printed graphite macro electrodes

Author affiliations

Abstract

The electroanalytical determination of selenium(IV) via anodic stripping voltammetry is shown to be possible for the first time using screen printed graphite electrodes. The deposition potential and time was optimised allowing a linear range from 10 to 1000 μg L−1 in 0.1 mol L−1 HClO4 to be realised with a limit of detection (3σ) found to correspond to 4.9 μg L−1. Utilising these screen printed graphite electrodes, the detection of selenium(IV) in drinking (tap) water is shown to be feasible allowing a detection limit (3σ) of 19.2 μg L−1 to be realised which is below the levels set by the United States Environmental Protection Agency. Such an approach suggests the possibility of a disposable screening tool for selenium(IV) in drinking water samples.
