Behaviour of Solutions of Tetraalkylammonium Salts in Ethyl Bromide as Liquid Membranes

Solutions of tetraheptylammonium bromide, iodide, nitrate, or perchlorate in ethyl bromide behave as anionic liquid membranes with ideality degrees close to 100%. In the cases of tetra­ heptylammonium fluoride, or chloride, the ideality degrees are about 80%. A picture of the charac­teristics and structures of this class of membranes is given
