'J;he redox surface film of Prussian Blue (PR) is studied for its electrochemical properties in contact with I non-aqueous solutions in acetonitrile (ACN), dimethyl formamide (DMF) and dimethyl sulphoxide
i (DMSO). The Cyclic VoItammetric (CV) results are quite interesting as they tend to be irreversible in contrast to the behaviour in aqueous medium. Surface coverage from CV data showed an increase in the
order of H20> ACN > DMF > DMSO. A similar trend is reflected in the facile intercalationldeintercalation proceSSl::S of hydrated and solvated potassium ion computed from double potentia) step chronoamperometric studies. Diffusion coefficients and heterogeneous electron transfer rate constants are elucidated by processing I-t transients
