L’extraction liquide/liquide et la complexation d’ions correspondent à des processus multi-étapes complexes mettant en jeux des phénomènes interfaciaux non élucidés. Nous étudions ici l’extraction de Eu3+ à partir de solution aqueuses de Eu(NO3)3 ou de Eu(Tf2N)3 par des ligands bis-1,2,4-triazinyl pyridine (BTP) vers deux LI ([BMI][Tf2N] et [OMI][Tf2N]), ainsi que vers l’octanol. Pourquoi l’extraction vers des LI est-elle plus efficace que vers les milieux organiques classiques ? Que se passe-t-il à l’interface avant et lors de l’extraction ? Quelle est la séquence de complexation ? Quel est le lieu de rencontre de L et Eu3+ ? Comment fonctionnaliser le ligand pour le rendre plus tensioactif ? Pour répondre à ces questions, nous avons simul...
