Abstract

By taking advantage of the SCN−catalytic effect on the extraction of Pd(II) by Kelex100 (7-(4-ethyl-1-methyloctyl)-8-quinolinol) a liquid supported membrane has been developed to extract Pd(II) from chloride solutions. Chemical parameters such as concentrations of Kelex100, SCN−and stripping agents were varied to determine their influence in the Pd(II) permeation. Different complexing agents of Pd(II) were studied for the stripping solutions, e.g. thiocyanate, thiosulfate and thiourea. Thiocyanate and thiourea were the most effective. Dodecanol and non ionic surfactants e.g. Span80, were incorporated, as organic modifiers. Such addition decreases the permeability of Pd(II). © 1992 Elsevier B.V.
