The permittivity and dielectric loss factors for exchanged forms of zeolithe type A have been measured. In radiofrequencies, wide dielectric loss peaks are always observed. The authors develop an analysis method to obtain rapidly the Debye dispersions derived from Cole and Cole plots when these dispersions exist. They use the derivative properties of plots ε' = G(ε"/f) and ε' = H( ε"f). They indicate the proposed numerical process and examine the method validity with well known examples. The authors prove the possibility of decomposing the experimental Cole and Cole plots of zeolite into a few Debye dispersions. They assign each Debye dispersion to a cation population which exists in the cavities. By means of a suitable model, the relaxatio...
