Probing the existence of uranyl trisulfate structures in the AMEX solvent extraction process.

Knowledge of the complex microstructure in solvent extraction phases is mandatory for a full comprehension of ionic separation. Coupling EXAFS with MD simulations for uranyl extraction in sulfuric media with tertiary amine extractants enabled unravelling of the unprecedented uranyl tri-sulfate structure.
