Summary:In the present paper, the electrochemical properties of magnetic iron oxide nanoparticles (Fe2O3 and Fe3O4) as highly sensitive sensors for the simultaneous determination of hydrazine and hydroxylamine was described. The electrochemical behavior of hydrazine and hydroxylamine was investigated using cyclic voltammetry, chronoamperometry and differential pulse voltammetry techniques. The results show that, at the modified electrode surface, the peaks of hydrazine and hydroxylamine oxidation were clearly separated from each other. Based on differential pulse voltammetry, the oxidation of hydrazine exhibited the dynamic range between 1.0- 1000.0 µM, and the detection limit (3σ) was 0.65 µM. These features will facilitate the determination of hydrazine and hydroxylamine in samples at a magnetic iron oxide modified electrode.
