Polarized liquid/liquid interfaces can be used to control ion‐exchange processes. This concept is illustrated with respect to zeolites, specifically with the replacement of Na + with H + ions in zeolite Y. The schematic diagram shows the ion exchange in a zeolite suspended in an aqueous phase with the selective extraction of Na + ions into an organic phase.
