Temperature effect in the ion transfer kinetics at the micro-interface between two immiscible electrolyte solutions
Original language description
Electrochemical impedance spectroscopy (EIS) was used to investigate the kinetics of the tetraethylammonium (TEA+) ion transfer across the water/1,2-dichloroethane (DCE) interface supported at the tip of a thick-wall microcapillary at various temperatures. EIS measurements were carried out at the equilibrium Galvani potential difference, which was controlled by the partition of TEA+ present in both the aqueous and DCE phase. The apparent standard rate constant k0 of the TEA+ ion transfer and the diffusion coefficient Dw of TEA+ in the aqueous phase were determined at five temperature values in the range 15?35 °C. The values k0 = 0.470.12 at 20 °C and k0 = 0.520.17 cm s1 at 25 °C agree well with those obtained by EIS and noise analysis under the same orsimilar experimental conditions in our previous studies. Comparable effects of temperature on k0 and Dw, as indicated by nearly equal slopes of the plots of log k0 and log Dw vs. the reciprocal absolute temperature, point to the absence
