Abstract
A graphite screen printed electrode was modified with iron oxide nanoparticles (Fe3O4 NPs). This modified electrode is proposed for electrochemical detection of hydroxylamine. Nanoparticles act as catalysts and also increase the surface area. Under optimized conditions, the oxidation peak currents, obtained by differential pulse voltammetry, of hydroxylamine increased linearly with increases in this concentration in the range of 1.0–125.0 μM. In this analysis, the detection limit was 0.4 μM. The developed electrochemical sensor was successfully applied to determine hydroxylamine in water samples.
