Název v původním jazyce

Limited Agreement between the Interfacial Tension and Differential Capacity Data for the Polarised Water|1,2-dichloroethane Interface

Popis výsledku v původním jazyce

Quasi-elastic laser light scattering and impedance measurements at water/1,2-dichloroethane interface are used to evaluate the interfacial tension and the differential capacity, respectively, as a function of the interfacial potential difference. Over the range of the potential differences around the zero-charge potential difference, the surface charge density obtained by integration of the capacity agrees well with that obtained by derivation of the interfacial tension. However, the ratio of these twocharges starts to deviate significantly from unity close to the potential window limits, where the faradaic current associated with the transfer of the supporting electrolyte ions becomes more pronounced, and where the capacity shows a remarkable enhancement. In the range of the potential differences, where the capacity data can be reliably obtained, a weak effect of the nature of the organic electrolyte on both the interfacial tension and the differential capacity is observed.
