摘要：A novel method for sensing potassium ions in aqueous solutions is presented. This method is based on the Prussian blue (PB) modified tin oxide (TO) electrode. Thin films of PB (KFeFe(CN)6), deposited onto transparent TO substrate, are reduced to Everitt’s salt (ES, or K2FeFe(CN)6) in solutions containing potassium ions. Using an in situ measurement of the absorbance changes in PB thin film while applying different reductive potentials to the electrode, the PB mole fraction within the thin film, x, can be obtained for solutions containing various concentrations of potassium ions. By applying either the theory of regular solution (0.25
