• Palladium
• Solvent extraction
• Diisopentyl sulphide

Diisopentyl sulphide (DIS) was used in an extract for Pd(II) from hydrochloric acid media. Palladium (II) was extracted quantitatively from 0.1 M HCl with diisopentyl sulphide concentration, contact time of aqueous and organic phases, organic/acqueous (O/A) phase ratio, ammonia concentration and hydrochloric acid concentratin of aqueous phase, were studied. Diisopentyl sulphide and Pd (II) form a 2:1 adduct (Pd(DIS)(2)Cl-2 in the extraction. X-Ray crystral determination revealed taht Pd(DIS)(2)Cl-2 is square-planar complex in which diisopentyl sulphide acts as a neutral unidentate ligand coordinated with palladium(II) via the sulphur atom of the diisopentyl sulphide.
