Polyurethane foam impregnated with ${\beta}$-diphenylglyoxime has been applied to the extraction of palladium(II) from platinum(IV) and nickel(II) in aqueous solution. Palladium(II) is quantitatively extracted from $0.01{sim}0.05M$ HCl. On the other hand, platinum(Ⅳ) was slightly extracted and nickel(II) was not found to be extraction in the same experimental condition. Based on the results obtained, the selective separation, removal and recovery of Pd(II) from Pt(IV) or Ni(II) was possible by batch or elution method.
