Aluminum electrode modified with manganese hexacyanoferrate as a chemical sensor for hydrogen peroxide.

A chemically modified electrode was fabricated based on manganese hexacyanoferrate (MnHCF) film. The MnHCF was used as a modifier immobilized onto an aluminum electrode. Stability of the electroactive film formed on the Al electrode surface indicated that MnHCF is a suitable material for the preparation of modified electrodes. The analytical applicability of the modified electrode for the determination of hydrogen peroxide was examined. A linear response in concentration range of 6.0x10(-7)-7.4x10(-3) M (r=0.9997) was obtained with detection limit of 2.0x10(-7) M for the determination of hydrogen peroxide. The modified electrode exhibited a good selectivity for H(2)O(2) in real samples. The mentioned electrode has advantages of being highly stable, sensitive, inexpensive, ease of construction and use.
