Abstract It has been demonstrated that tetra-amino iron phthalocyanine can be polymerized onto a glassy carbon electrode by electrooxidation of the monomer in solution. Organic peroxides can be catalytically reduced at such polymeric film modified electrode. While on a bare glassy carbon electrode, none of the peroxides can be reduced within the potential range studied. When used in flow injection analysis, the modified electrode permits the detection of these compounds by reduction mechanism at higher potentials without the interference from oxygen. The response is stable and has a wide dynamic range.
