Abstract
AbstractDecyl isonicotiniate and decyl nicotiniate permit a rapid extraction of palladium(II) from its hydrochloride solutions. Decyl picoliniate is not a suitable extractant. 4‐Octylphenylamine can act as a phase transfer catalyst when its concentration in the organic phase is at least 2·5 × 10−4 M. It seems that the interfacial adsorption of pyridine carboxylates and of 4‐octylphenylamine is not the decisive phenomenon in palladium(II) extraction. The negligible protonation of the pyridine‐type extractants and the phase transfer catalysis explains well the quick extraction of palladium(II) with the commercial and highly hydrophobic extractant ACORGA CLX‐50.
