Abstract: | The extraction of Nd(III), Tb(III) and Lu(III) as representatives of lanthanide(III) ions with picrolonic acid (HPA) in methylisobutylketone (MIBK) has been studied from pH 1-2 buffer solutions. The composition of the organic species formed in the organic phase after extraction has been determined by slope analysis to be M(PA)3 [M = Nd(III), Tb(III) and Lu(III)]. The equilibrium constant values, log k ex This revised version was published online in July 2006 with corrections to the Cover Date. |
