  Micro emulsions (MEs) offer an exceptionally broad spectrum of applications
covering sensing, electrosynthesis, supercapacitors and redox-flow batteries.
Herein, we develop the theory for a sophisticated electrochemical
characterizion of MEs with a spatially and time-invariant anisotropy in the
diffusion domain by means of cyclic voltammerty (CV). By introducing spatially
dependent diffusion coefficients into Ficks' first law, we derive a modified
diffusion equation to simulate any inherent anisotropy of the ME under
investigation. Moreover, by formulating an extended second-order homogeneous
six-member square scheme for a kinetically controlled two-step two-electron
reaction we capture the intricate entanglement of chemical and electrochemical
equilibria. Our theoretical concept is finally validated by experimental CV
data for the ME based two-step redox reaction of methyl-viologen which paves
the way for a quantitative electrochemical characterization MEs.
