Description
A general approach to liquid-liquid extraction will be developed through notions of thermodynamics and kinetics, with a view to understanding the mechanisms responsible for extraction as well as the processes taking place at the liquid-liquid interface. Fundamental aspects of other types of extraction (liquid-solid, supercritical fluid, distillation) will also be covered.

CM: 12h
TD : 8h
Objectives
The objective of this teaching unit is to inventory the fundamental data on the kinetics and thermodynamics of liquid-liquid extraction. It will also present the main concepts and processes inherent in extraction (liquid-liquid, liquid-solid or by critical fluid) and distillation.
Necessary prerequisites
Solution chemistry
Solution chemistry supplements
Solution chemistry applied to actinides
Knowledge control
Full continuous assessment
