The theoretical potential-time dependence corresponding to the electron transfer reaction proceeding at the interface between two immiscible liquid phases with the redox pairs O1/R1 in the aqueous (aq) phase and O2/R2 in the non-aqueous (non) phase, that is complicated by the reaction R1(aq) + Z(aq) → O1(aq) in the aqueous phase, has been derived under the galvanostatic conditions. Moreover, a method for the determination of the formal rate constant kf for the given homogeneous chemical reaction is proposed.

Kinetics Of

Kinetics of electron transfer between ferrocene or its derivative (1,1'-diethyl- or 1,1'-distearoylferrocene) in dichloroethane and hexacyanoferrate(III) in water was studied by means of convolution potential sweep voltammetry. Within the accessible range of experimental conditions no effect of either the potential or concentrations of reactants on the rate constant of electron transfer from the organic to the aqueous phase (ko→w = 1 . 10-7 m4 mol-1 s-1) was observed. Electron transfer was shown to occur far from the potential range, in which the ferricenium ion transfer can take place. However, the reaction was complicated by the chemical decomposition of ferricenium in dichloroethane (k = 0·346 s-1).

Thin Film Formation

A thin film was formed through in vitro CaCO3 crystallization in the presence of complex coacervates, which was expected to be planar and poorly crystalline CaCO3 guided at the interface of two immiscible liquid phases upon complex coacervation.
