Monovalent/monovalent and divalent/monovalent ion exchange in hexadecyltrimethylammonium hydroxide (CTAOH), a relative counterion type micelle, was investigate by using as a probe the dehydroshlorination reactions of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT) and 1,1-dichloro-2,2-bis(p-chlorophenyl)ethane (DDD).Selectivity coefficients for the ion exchange of bromide, chloride, fluoride, nitrate, acetate, sulfate, and carbonate anions with the reactive counterion (OH^-) and between the anions themselves were evaluated from the kinetic treatment of the data using a simple pseudophase ion-exchange-type formalism.
