Abstract
Trimethylene-bis(n-butyl) xanthate (TrMBnBX) has been synthesized as a new sulfur-containing reagent for the extraction of precious metal io ns. This compound exhibited high selectivity for extraction of PCI(II) and Ag(I) ions in dichloroethane, over Pt(IV), Au(III) and most of th e base metal ions. A mixed aqueous system containing H2SO4 in Presence of small amount of chloride ions provides the maximum extraction of P d(II), where it forms a 1:1 complex with TrMBnBX.
