Abstract Interactions of ionophore monensin with heavy metal monovalent cations, Ag+, Tl+, Hg 2 2+ , were studied in methanol and in various biphasic waterorganic solvent systems to supplement previous data on alkali-metal cations. The species formed were identified and the corresponding formation constants determined. Enthalpies of formation were also obtained in methanol for Ag+ and Tl+ from calorimetric measurements. The results for monovalent cations in general are discussed in terms of cation size and solvation, and structure of the ionophore anion.
