Özet

Extraction of Co(II) and Ni(II) from aqueous HCl solutions into organic Alamine 336-m-xylene systems were studied. Extraction experiments were repeated for three initial metal concentration ratios with total initial metal concentration of 7 g L- 1, each at 1, 5 and 10 M HCl. The extraction percentage, E, in terms of volume percentage of Alamine content, Ve, in solvent mixture, were determined for each metal. Optimal Alamine 336 contents were reported for a single stage extraction. The amine loading factor and separation factor values were also determined in terms of Ve. Alamine 336 was found to be a suitable extracting and separating agent for Co(II)-Ni(II) containing solutions at 5 M HCl. © 2008 Elsevier B.V. All rights reserved.
