Abstract: The extraction of Europium (Ⅲ) from perchloric acid solution with mixtures of l-phenyl-3-methyl-4-benzoyl-pyrazolone-5 (PMBPor HA) and diphenyl sulfoxide (DPSOor B) in toluene has been investigated.The formulas of the extracted species have been shown to be ErA3·HA, ErA3·Band ErA3·2B. Their extraction equilibrium constants and thermodynamic parameters of the enthalpy change (ΔH) Gibbs free energy change (ΔG) and entropy change (ΔS) have been calculated at 298.2K.
