The transfer behavior of both acidic and basic dyes at the interface between water and some organic solvents has been studied in detail by electrochemical methods, and a transfer mechanism is proposed for both acidic and basic dyes. The equations of interfacial half-wave potentials for both dyes are deduced in terms of the mechanism and are consistent with the experimental data, respectively. Apparent standard transfer potentials ABrp" and Gibbs energies A,"G' are calculated. The effect of dye structure and the nature of organic solvent on the transfer of dye are discussed in detail and a linear empirical relationship between interfacial half-wave potential and dielectric constant of organic phase is inferred for both acidic and basic dyes.

The impedance or admittance measurement of ion transfer across immiscible electrolyte interfaces involves measuring quantities which are non-linear functions of frequency and model parameters. To extract the kinetic information from the data, non-linear regression techniques must be used. A Quasi-Ne
