Abstract
In this research, a new electrochemical sensor was developed for the determination of hydrogen peroxide (H2O2) in the milk samples. The proposed electrode was fabricated using a glassy carbon electrode modified with layered double hydroxide magnetic Fe3O4 nanoparticles (FeCu-LDH@Fe3O4/GCE). The resulting FeCu- LDH@Fe3O4 was studied and characterized using different methods including field emission scanning electron microscopy, x-ray diffraction, and infrared spectroscopy in addition to the electrochemical methods. After optimization of affecting parameters, the FeCu-LDH@Fe3O4/GCE exhibited a high electrocatalytic activity for H2O2 electroreduction and high cathodic peak currents were obtained. The proposed electrode also illustrated a wide linear dynamic domain in the range of 2 to 400 μM and low limit of detection (S/N = 3) was calculated to be 0.6 μM. Finally, the proposed sensor was sucessfully employed for the quantification of H2O2 in milk samples.
