▎ 摘　　要

Prussian blue (PB) and graphene oxide (GO) were synthesized and characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy among others. The synthesized Prussian blue and graphene oxide were used in the modification of glass carbon electrodes for the chemical detection of hydrogen peroxide at pH 3, 5.12 and 7.4. Cyclic and square wave voltammetry of GC-PB and GC-GO-PB electrodes show significant cathodic and anodic detection of hydrogen peroxide predominantly at pH 5.12 and 7.4 indicating one electron transfer reaction at the electrode surface.
