Extractive recovery of palladium(II) from a hydrochloric acid solution with quaternary phosphonium salt: trihexyl(tetradecyl)phosphonium bis-(2,4,4-trimethylpentyl)phosphinate (Cyphos®IL 104) as a novel reagent in the presence of toluene has been investigated. Extraction data indicate that Cyphos®IL 104 is a very efficient and fast extractant. The increase in HCl concentration has negative influence...
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 following order: iron(II)<zinc(II)<iron(III). Zinc(II) extraction is preferred over iron(II) when both...
