The absorption of microquantities of bromide ion from aqueous solutions of hydrochloric acid, lithium, sodium, potassium, and cesium chlorides by tri-n- octylamine solutions in toluene, and from hydrochloric acid by a strongbase anion exchanger, was measured. The departure of the equilibrium distribution coefficients for the liquid ion exchanger from a mass law'' dependence on electrolyte concentration could be explained quantitatively by the non ideality of the aqueous phase except for the concentrated hydrochloric acid solutions. With the anion-exchange resin, however, corrections for aqueous phase non- ideality and for de-swelling were not sufficient to cause the distribution data to conform to the mass law; in addition, an important correction for the organic phase non-ideality was required. The magnitude of the organic phase non-ideality could be correlated with the invasion of this phase by electrolyte. WWhen the invasion was small, or absent, as with the liquid exchanger, the non-ideality was small and could be neglected. (auth)
