EnglishCopper hexacyanoferrate thin films were potentiodynamically deposited on glassy carbon electrodes and employed for the chronoamperometric detection of hydrogen peroxide at 0.0V vs. SCE. A new experimental procedure based on the intercalation of copper ions inside the structure of the films led to sensors with improved performances. The modified electrode displayed an increased sensitivity to hydrogen peroxide detection together with a wider linear response range and a lower detection limit. Furthermore, even if the electrode response decreased with use, the initial activity could be restored by performing a new intercalation procedure.
