Abstract
Ammonia diffuses selectively through poly(vinylammonium thiocyanate) membranes. This high selectivity occurs because the membranes react with ammonia to produce a solution of poly(vinylamine) and ammonium thiocyanate, a salt in which ammonia is highly soluble. Liquid membranes made of ammonium thiocyanate and membranes of polyvinyl alcohol) impregnated with ammonium thiocyanate show similar behavior. None of these membranes operate by means of mobile carriers, the mechanisms most often responsible for selective facilitated diffusion.
