What is Electrochemistry of ionophore-coordinated Cs and Sr ions in the tri-1-butylmethylammonium bis((trifluoromethyl)sulfonyl)imide ionic liquid about?
The selective extraction of Cs + and Sr 2+ from aqueous solutions by using the ionophores calix [4]arene-bis(tert-octylbenzo-crown-6) (BOB-CalixC6) and dicyclohexano-18-crown-6 (DCH18C6), respectively, was demonstrated in the hydrophobic, room-temperature ionic liquid (RTIL), tri-1-butylmethylammonium bis((trifluoromethyl)sulfonyl)imide (Tf 2 N -). The electrochemistry of Cs + coordinated by BOBCalixC6 and Sr 2+ coordinated by DCH18C6 was examined at a mercury film electrode (MFE) in this ionic liquid by using cyclic staircase voltammetry, sampled current voltammetry at a rotating electrode, and chronoamperometry. Both BOBCalixC6•2Cs + and DCH18C6•Sr 2+ exhibit well-defined reduction waves at approximately -2.4 and -2.9 V versus the ferrocene/ferrocenium (Fc/Fc + ) couple, respectively, in which the coordinated ions are reduced to their respective amalgams, permitting the recycling of the ionophores. The diffusion coefficients of BOBCalixC6•2Cs + and DCH18C6•Sr 2+ are (2.7 ± 0.1) × 10 -9 and (2.1 ± 0.1) × 10 -9 cm 2 s -1 , respectively, at 30 • C. The coulometric efficiency for the reduction and stripping of Cs at mercury pool electrodes was about 90% and was independent of the dep
