| Abstract: | The potential windows of the system water/pure solvent (W/P) and water/solvent mixtures(W/S) have been investigated by cyclic voltammetry with solvents whose dielectric constants lie between 5.67 and 34.82. In the presence of LiCl in the aqueous phase and tetrabutytammoniumtetraphenylborate(TBATPB) in the organic phase, the systems water/allyl iso-thiocyanate (W/AIT) and water/nitrobenzene (W/NB) show a same wide potential window. Thermodynamic parameters of ion transfer across W/AIT interface were determined. In systems of W/P and W/S the influence solvent effect on the standard Gibbs energies of transfer of ion Δ_o~wG_(tr,i)~p was discussed. |
