We report some details of the ferrocyanide and ferricyanide complexes immobilized in chitosan. These immobilized complexes are characterized by electrochemistry, and infrared and Mössbauer spectroscopy. Alterations are observed in the infrared and Mössbauer spectra and in the cyclic voltammograms of the material prepared with ferricyanide when this material is irradiated with sunlight. These alterations indicate that the ferricyanide ion undergoes a photoinductive reduction on the biopolymeric surface.
