hydrochloric acid - Opis:
- Extraction of zinc(II) and iron(III) from hydrochloric acid solutions using quaternary phosphonium salts, CyphosŽ IL 101, CyphosŽ IL 104, CyphosŽ IL109 and CyphosŽ IL 111 in mixtures with toluene, was studied. Trihexyl(tetradecyl)phosphonium chloride (CyphosŽ IL 101) and trihexyl(tetradecyl)phosphonium bis(2,4,4-trimethylpentyl)phosphinate (CyphosŽ IL 104) showed the best zinc(II) and iron(III) extraction abilities. After three stages of zinc(II) extraction with CyphosŽ IL 101 and CyphosŽ IL 104 the efficiencies were 100 and 93.6%, respectively. Total iron(III) transport to the organic phase was achieved after two separation stages and amounted to 82.1 and 100% for CyphosŽ IL 101 and CyphosŽ IL 104, respectively. Zinc(II) and iron(III) could be effectively stripped from the loaded organic phases with 0.5 mol dm-3 sulfuric acid. The more hydrophobic the character of the anion type of phosphonium salts, the lower the efficiency of extraction.
