Extraction and theoretical study on the complexation of the strontium cation with beauvericin
Original language description
From extraction experiments and ?-activity measurements, the extraction constant corresponding to the equilibrium Sr2+(aq) + 2A?(aq) +1(nb) reversible arrow 1.Sr2+(nb) + 2A(nb) taking place in the two-phase water?nitrobenzene system (A = picrate, 1 = beauvericin; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as log Kex(1.Sr2+,2A) = 0.6 0.1. Further, the stability constant of the 1.Sr2+ complex in nitrobenzene saturated with water was calculated for a temperature of 25 °C: log ?nb(1.Sr2+) =8.5 0.1. Finally, by using quantum-mechanical DFT calculations, the most probable structure of the resulting cationic complex 1.Sr2+ was derived.
