In this work, a novel hydrogen peroxide electrochemical sensor was constructed with ferroferric oxide(Fe_3O_4) magnetic nanoparticles, which demonstrated good electrocatalytic activity for hydrogen peroxide. There existed a good linear relationship between the concentration of hydrogen peroxide and the oxidation peak current in the range of 1.00 × 10~(-6)~ 1.00 × 10~(-3) mol·L~(-1)(R =0.9980) with the detection limit of 6.60 × 10~(-7) mol·L~(-1). The sensor exhibited good anti-interference ability, high reproducibility and stability.
