Abstract
Facilitated ion transfer reactions of the ammonium, potassium, and sodium ions with the ionophores dibenzo‐18‐crown‐6, nonactin, and valinomycin were investigated at the water/ 1, 2‐dichloroethane interface. Association constants for the various reactions studied were calculated to determine the selectivity imparted by the ionophores on the transferring ions. Of the ionophores studied, nonactin was found to be the most selective towards the ammonium ion, with a calculated association constant of 14.1.Keywords
