Abstract

The liquid-liquid extraction of neodymiumIII from succinate media 0.06 M has been studied at pH 6.0 with the solution of 0.1 M of N-n-octylaniline in xylene when equilibrium is maintained for 5 min. The back-extraction of neodymiumIII has been performed by using 0.1 M HClO4. The effect of various parameters, such as pH, equilibrium time, extractant concentration, stripping agents, organic diluents, and aqueous to organic volume ratio on the extraction of neodymiumIII has been studied. On the basis of slope analysis, the stoichiometry of the extracted species was determined as 1 : 1 : 2 RR′NH2+Ndsuccinate2−org. The method is free from interference of large number cations and anions. The method was used for the selective extraction of neodymiumIII from its binary mixture with UVI, ZrIV, NbV, LaIII, ThIV, CeIV, and YIII. The proposed method is selective and was successfully applied to the synthetic mixtures to show the practical utility of the extractant.
