Kinetic analysis of electrochemically induced ion transfer across a single microdroplet ∣ water interface

Mass transfer dynamics of an electrochemically produced ferrocenium cation across a single-nitrobenzene-microdroplet ∣ water interface were studied on the basis of micromanipulation and microelectrode methods. Cyclic voltammograms of ferrocene in single droplets were analyzed as a function of a potential sweep rate and a liquid-junction potential between the droplet and water. The interfacial ion transfer processes of the ferrocenium cation are discussed kinetically.
