Resumen

A selectivity coefficient for the foam separation of Fe(CN)₆ ^4- Ag(S₂O³)₂ ^3-, Cr₂O₇ ^2- S₂O³ ^2- HPO₄ ^2-, and I^- from solutions containing ethylhexadecyldimethyl ammonium bromide is related to the absolute partial molal entropy of each ion. The entropy, which correlates well with the degree of hydration, enables an estimate of the selectivity of an ion flotation or foam fractionation by a surfactant.
