The permeation mechanism has been studied to obtain fundamental information for developing liquid membrane process. Chloride ion was concentrated across a diaphragm-type liquid membrane impregnated with Amberlite LA-II as a mobile carrier. This process is considered to constitute a kind of active transport process.
The permeation rates of chloride ion are explained approximately by a permeation model in which hydrochloric acid reacts with the carrier at the interface of one side of the membrane and the complex formed by the reaction then diffuses through the membrane and further reacts with sodium hydroxide in the vicinity of the opposite interface.
