Fundamentals and Applications in Electrochemistry of Liquid-liquid Interfaces

Abstract The interface of two immiscible electrolyte solutions (ITIES) has generated great interest since it can be used to understand several processes in chemistry and biology. The transfer process of ions and organic molecules of environmental and pharmacological importance have been study across the ITIES. In the present work, a small introduction to the study of ITIES is given, as well as the interpretation of the cyclic voltammetric experiments regarding to the transport of an organic cation (TEA + ) across the interface. Finally, examples of application of studies of ITIES: a) the transfer of terbutryne herbicide and b) electron transfer reaction between a redox pair (Fe(CN) 6 4-/ Fe(CN) 6 3) and isoperezone across the water|1,2- dichloroethane interface are discussed.
