Abstract :
This research aimed to develop a novel sensing platform for hydrogen peroxide (H2O2) quantification in the milk
samples. The proposed sensor was fabricated using a glassy carbon electrode modified with Fe-Cu layered double
hydroxide (LDH)/magnetic Fe3O4 nanoparticles (FeCu-LDH@Fe3O4/GCE). The resulting sensor was characterized
using field emission scanning, electron microscopy, x-ray diffraction, and infrared spectroscopy, with the addition
of 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 was calculated to be 0.6 μM.
