摘要
An equation to express ion exchange selectivity coefficient was derived and used for cal- culating that of PPY film with the results obtained by cyclic voltamrnetric measurement.PPY film was synthesized by electrochemical method in aqueous solution using K_4Fc(CN)_6 as supporting electrolyte, and the anions were doped into the film.Ion exchange behaviour of doped Fe(CN)_6^(3-/4-)in the PPY film with Cl^-,NO_3^- or F^- ions in solution has been studied,and the corresponding ion exchange selec- tivity coefficients were determined.
