DETERMINATION OF SOME ELECTRICAL PARAMETERS FOR UO2(O3PC6H5) FILMS DEPOSITED ON A POROUS SUPPORT

The electrical behaviour of a uranyl phenylphosphonate (UPP) film in e lectrolyte media has been studied by impedance spectroscopy, salt diff usion and concentration potential and some electrochemical parameters such as cation transport number, salt diffusion coefficient and ionic permeability in the film were determined. The equivalent circuits asso ciated with the film and the film/electrolyte interface, which consist of a parallel association of a non-ideal capacitor, were also obtaine d. Both parameters were calculated when the generating precipitate sol utions UO2(NO(3)0)(2) and H2O3PC6H5, were bathing the UPP film. Concen tration dependence of all these parameters was also considered.
