Abstract: | From extraction experiments and γ-activity measurements, the exchange extraction constants corresponding to the general equilibrium M+(aq) + Cs+(org) ⟺ M+(org) + Cs+(aq) taking place in the two-phase water–phenyltrifluoromethyl sulfone (abbrev. FS 13) system (M+ = Li+, H3O+, Na+, NH4+ hbox{NH}_{4}{}^{+} , Ag+, Tl+, K+, Rb+; aq = aqueous phase, org = FS 13 phase) were evaluated. Furthermore, the individual extraction constants of the M+ cations in the mentioned two-phase system were calculated; they were found to increase in the series of Li+ < H3O+ < Na+< NH4 + hbox{NH}_{4}{}^{ + } < Ag+ < Tl+ < K+ < Rb+ < Cs+. |
