Solution chemistry applied to actinides

A general approach of the aqueous solution chemistry of actinide elements will be developed through notions of thermodynamics and kinetics, redox potentials, hydrolysis and complexation. In order to support these notions, concrete examples from industry, recycling or environment will be discussed.

Hourly volumes* :

            CM : 11h

            TD : 9h

The objective of this teaching unit is to approach the chemistry of actinide elements in aqueous solution and to apply them to concrete examples (industry, recycling, environment, ...).

Basic elements in radioactivity

Complements in solution chemistry

Continuous control

• Case of single-phase aqueous solutions containing actinide elements:

            - Generalities (thermodynamics and kinetics of reactions, ...)

            - Redox potentials and electrochemistry (dismutation, ...)

            - Hydrolysis - complexation (E/pH diagram, ...)

• Case of two-phase systems containing actinide elements:

            - Precipitation

            - Liquid - liquid extraction

            - Ion exchange resins

• Case of complex media (molten salts, ionic liquids, ...)

            - Effect on the reactivity of actinides in solution

The teaching will include tutorials applied to questions with an applied origin, but also analyses of experimental results obtained in the context of scientific publications.
