| Abstract: | The extraction of lanthanide ions(La3+, Nd3+, Dy3+, Yb3+) from niuie acid solution with mixturc of 1-thenyl-3-methyl-4-dichloroacetyl-pyrazolone-5(PMDCP) and tri-n-(octy-lphosphine oxide (TOPO) hae been studied. The synergic extraction coefficent of lanthanum 27.3. The composition of extracted compound of lanthanum was shown to be La(PMDCP)3·(TOPO)2. The pH values of half an, extraction rate at 25℃ of La3+, Nd3+, Dy3+ and Yb3+ are 2.11, 1.77, 1.60 and 1.50 respectively. The extraction equilibrium constants, enthalpy cha-nge and entropy change of the reaction at 25℃ have also been calculated. |
