Solution chemistry
Article study, multiple choice questions, and terminal exam
Aqueous solutions :
– Diluted, concentrated, complex solutions
– Activity, activity coefficient (Debye and Hückel models, Davies, Theory of specific interactions, Pitzer model).
– Complexing: successive or global formation constants, complexing coefficient, distribution diagram, action of acidity on the complexing coefficients.
– Types of ligand (H, OH, L), multi-ligand complexation,…..
Chemical separations :
– Solubilization / precipitation
– Liquid/liquid extraction: principle, simple or complex equilibria
– Extraction phenomenon: co-extraction / ion exchange
– Synergism, release
– Liquid/solid extraction: ion exchange resins, distribution equilibria, complexing effect
Non-aqueous reaction media:
– Micellar media (presentation, micelles for separations, three-phase system, cloud point, liposomes, microemulsions for extraction)
– Molecular solvents (solvation, acid-base properties, ion pairs…)
– Molten salt media: molten salts at high temperature (presentation, oxoacidity, extraction applications) and ionic liquids (presentation, some properties, extraction applications)
– Supercritical fluids (presentation, some properties, extraction applications)
Articles are studied and criticized.
Understanding and control of solution interactions for the purpose of separating and samples treatment in complex matrices.
The applications presented are varied with an emphasis on nuclear and environmental issues.
