摘要：

From extraction experiments and gamma-activity measurements, the extraction constants corresponding to the general equilibrium Cs(+)(aq) + A(-) (aq) double left right arrow Cs(+)(org) + A(-) (org) taking place in the two-phase water-phenyltrifluoromethyl sulfone (FS 13) system (A(-)= I(-), ClO(4)(-), MnO(4)(-), Br(3)(-), I(3)(-), picrate, tetraphenylborate (BPh(4)(-)); aq = aqueous phase, org = FS 13 phase) were evaluated. Furthermore, the individual extraction constants of these 7 anions in the mentioned two-phase system were calculated; they were found to increase in the series of I(-) < ClO(4)(-) < Br(3)(-) < MnO(4)(-), picrate < I(3)(-) < BPh(4)(-).
