中文摘要	a study of potassium ion transfer across a water \ 1,2-dichloroethane (w \ dce) interface facilitated by dibenzo-18-crown-6 (db18c6) with various phase volume ratio systems is presented. the key point was that a droplet of aqueous solution containing a redox couple, fe(cn)(6)(3-)/fe(cn)(6)(4-), with equal molar ratio, was first attached to a platinum electrode surface, and the resulting droplet electrode was then immersed into the organic solution containing a hydrophobic electrolyte to construct a platinum electrode/aqueous phase/organic phase system. the interfacial potential of the w \ dce within the series could be externally controlled because the specific compositions in the aqueous droplet make the pt electrode function like a reference electrode as long as the concentration ratio of fe(cn)(6)(3-)/fe(cn)(6)(4-) remains constant. in this way, a conventional three-electrode potentiostat can be used to study the ion transfer process at a liquid \ liquid (l \ l) interface facilitated by an ionophore with variable phase volume ratio (r = v-o/v-w). the effect of r on ion transfer and facilitated ion transfer was studied in detail experimentally. we also demonstrated that as low as 5 x 10(-8) m db18c6 could be determined using this method due to the effect of the high phase volume ratio.
