Jm. Rosolen et al., THE MIRAGE EFFECT WITH A SUPPORTING ELECTROLYTE AT CONSTANT MASS-TRANSFER THROUGH THE DIFFUSION LAYER, Journal of electroanalytical chemistry [1992], 365(1-2), 1994, pp. 165-169
In this paper we discuss the effect of a supporting electrolyte on mir
age experiments in electrochemical cells and we report data showing th
e dependence of the mirage signal on the concentration of the supporti
ng electrolyte. Concentration profiles for all species present in the
electrolyte can be calculated exactly under specific requirements. The
mirage signal is then calculated as a function of the ratio of the co
ncentrations of the supporting and the electroactive electrolytes, and
the results are compared with the experimental data. This model allow
s calculation of the optical parameters of the supporting electrolyte
and not just those of the electroactive species.
