Solvent extraction of Palladium(II) [Pd(II)] from chloride solution has been investigated by using triphenylphosphine (Ph3P), triphenylphosphine oxide (Ph3PO) and triphenylphosphine sulphide (Ph3PS) as extractants in benzene. Under similar experimental conditions, Ph3P showed relatively better extraction of Pd(II) compared to the other two extractants. Therefore, detailed investigations on the effects of different parameters on the extraction of palladium by Ph3P were then carried out. The stripping of the extracted metal species using different stripping agents solutions was investigated and the selective removal of Pd was found to be when using 1 M stabilised thiosulfate solution. Based on the experimental results, an equilibrium model is proposed and the stoichiometry of the extracted species was found to be [Pd(Cl)2.2Ph3P]. Thermodynamic parameters including ΔG, ΔH and ΔS for the Pd-Ph3P extraction system were determined. IR spectrum analysis of the extracted complex indicates the direct extraction of Pd as chloride and bonding to phosphorus.
