Abstract: A novel microcavity Ag|AgCl electrode was fabricated to construct the micro_interface of two immiscible electrolyte solutions(ITIES). The transfer reactions of K + ion facilitated by DB18C6 across the water/1,2_DCE interface was investigated with the three_electrodes system. The corresponding reaction parameters were derived from the voltammetric data. The results showed that the microcavity electrode would be a useful and efficient tool to investigate the charge transfer reactions at ITIES.

Key words: Micro_cavity electrode, ITIES, Facilitated ion transfer
