Abstract:

Transport studies on interfaces between immiscible phases bridges the field of heterogeneous electrode electrochemistry and that of homogeneous solution chemistry. Early work on liquidliquid boundary was concerned with large area order of a square centimeter interfaces. Recent studies investigate phenomena on interfaces rendered in pores, capillaries and small holes. The behavior of such interfaces in the presence of dodecyl sulfate, forming micelles, is investigated. Voltammetry and amperometry on these small interfaces reveals that the accompanying voltammetric characteristics are similar to that of metal ultramicroelectrodes. Potentiometric studies of dodecyl sulfate on waternitrobenzene and aqueous polymer immiscible interfaces allow determination of critical micelle concentration.
