Compétences visées

Objectif de l’UE
· Integrate knowledge of the ionic and molecular recognition in different applications.
· Explain the physico-chemical phenomena that govern the transfer of an essentially hydrophilic metal ion to a hydrophobic organic phase. Experiment these concepts with solvent extraction in hydrometallurgy (application to the nuclear waste treatment).

Compétences développées et/ou évaluées
