Abstract: Afilm of Prussian blue (PB) was electrochemically deposited on a quartz crystal microbal-ance (QCM).The forming of the PBfilm was monitored in situ by the frequency shift of QCM, the PBfilm is an electroactive polymer film, during reduction of the film and subsequent reoxidation to PB, cation transport in and out of the film.This changes the total mass of the polymer film and alters the frequency of the QCM.From the frequency changes of the QCM, we found that K+, Na+, NH4+ can migrate in and out of the film easily, but it is difficult for Ca2+ to entet the film.

Key words: Quartz crystal microbalance, Prussian blue, Chemical modified electrode
