Selective removal of zinc(II) from spent pickling solutions in the presence of iron ions with phosphonium ionic liquid Cyphos IL 101

Trihexyl(tetradecyl)phosphonium chloride (Cyphos IL 101) – a phosphonium ionic liquid – was used as a novel reagent mixed with toluene to extract selectively zinc(II) from chloride media in the presence of iron(II). The extraction of individual metal ions with Cyphos IL 101 increases in the followin...
