NITROGEN REAGENTS IN METAL ION SEPARATION. PART 6 2-(r-OCTYLTHIOMETHYL)PYRIDINE AS EXTRACTANT FOR LATER 3d TRANSITION METAL IONS.

ABSTRACT

The new extractant 2-(r-octylthiomethyl)pyridine was synthesized and applied in dilute acid medium in the presence of chloride and thiocyanate ions, for the separation of later 3d transition metal ions. Good Cu(II) specificity was revealed in dilute chloride medium as well as very promising nickel(II) preference to iron(III). The extractant behaviour of the ligand was explained in terms of its coordination behaviour.
