Description: Das Projekt "FP5-EAECTP C, Selective extraction of minor actinides from high activity liquid waste by organized matrices" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Universität Mainz, Fachbereich Chemie und Pharmazie.Objective: High activity waste, which contain long life minor actinides, are currently vitrified for their storage in geological formation. In order to decrease the potential toxicity of this wastes the selective removing of these minor actinidesis studied in order to destroy them by transmutation. Currently the separation of americium and curium is a three stages process. Preceding projects showed the potentialities of the functionalized calixarenes which make possible to obtain a high intra class selectivity, for example for the alkali cations (separation cesium/ sodium) or discrimination of different lanthanides with respect to their size. In this project, calixarenes aimed to recover in one step americium and curium will be synthesized and studied. Moreover the process of extraction of cesium from the H. A. solutions by calixarenes-crown6 will be tested on real solutions in order to show the capacity of calixarenes to be implemented on H.A. solutions. Prime Contractor: Commissariat a l'Energie Atomique, Centre de Cadarache; France.
