In the french nuclear waste treatment strategy, actinides(III) / lanthanides(III) separation is one of the key step. This work is focused on the use of nanofiltration membranes and liquidliquid extraction processes to achieve this separation. These two techniques have been compared with hydrophilic organic compounds. New ligands have also been synthesized and evaluated on actinides(III) / lanthanides(III) separation by liquid-liquid extraction. Conditions have been optimized on an europium(III) / lanthanum(III) model. Finally, new inorganic membranes have studied for the europium(III) / lanthanum(III) separation. The different operating parameters have been studied such as pH, ionic strength and lanthanides concentration. Separation has bee...
