PH EFFECT OF AQUEOUS PHASE OF A 2-IMMISCIBLE LIQUID-PHASES SYSTEM ON ION TRANSFER ACROSS PHASE INTERFACE UNDER CONDITIONS OF ELECTROLYTE DROPPING ELECTRODE

The theoretical current-potential curves have been derived in the form Δorg(I) (Δorg is the Galvani potential difference between the aqueous and organic phase of a two-phase system; I is the mean current) describing the pH effect of the buffered aqueous phase on reversible transfer of ions, which are the products of dissociation equilibria in the aqueous phase, across the interface of two immiscible liquid phases under the condition of an electrolyte dropping electrode. On the basis of the derived current-potential dependences, the possibilities of the determination of the corresponding equilibrium constants are presented. © 1990.
